This document outlines the scope and usage of the \Yquant{} package.
It contains both a reference and a huge number of examples.
\Yquant{} is a package that makes typesetting quantum circuits easy; the package is available on CTAN.

Consequently, the user is restricted to the set of features that \pkg{qasm} directly offers (which is small).
Changes to the output, while possible, will be overwritten if \texttt{qasm2circ} is run again.
\pkg{qasm} output often looks sub\hyp optimal do to the fact that, e.g., rectangles are made up of four lines that do not properly connect and give a crumbly general feeling.

Being an external program, \pkg{qpic}'s intrinsic set of features (including, e.g., vertically set circuits) are huge.

A disadvantage of external programs is that the amount of space gates need is not accessible by the script; hence, manual intervention may be required.

\section{Basic elements of \Yquant}\label{sec:grammar}
\Yquant, as some of the aforementioned packages, builds on \TikZ.
Its basic syntax is similar to \pkg{pgfplots}: Start a \tex!tikzpicture! environment (perhaps passing some options); inside, start a \tex!yquant! environment.
-
+
Inside the \tex!yquant! environment, \TeX{} will now understand the \Yquant{} language---so \Yquant{} falls into the same category as \pkg{qasm} and \pkg{qpic}, providing a human\hyp readable language for the specification of the circuit that is not fixed to the actual layout.
-
+
However, \Yquant{} is a \TeX\hyp only package (actually, \hologo{LaTeX2e}, but not \hologo{LaTeX3}) that requires no external script to run---so it also falls into the same category as \pkg{qcircuit} and \pkg{quantikz}.
-
+
Since it runs entirely within \TeX, you can at any time interject \Yquant{} code with arbitrary \TeX{} or \TikZ{} code (though if it is ``too arbitrary,'' you may need to restart the \Yquant{} interpreter).

+ Sometimes, continued development shows that certain choices of interfaces, configuration, or behavior are less ideal than originally thought.

\subsection{Starred vs. unstarred environment}
You may choose to use either the \tex!yquant! or the \tex!yquant*! environment.
The former one requires you to define all your registers before you use them (though you may decide to define a register after some operations on \emph{different} registers, but before its first usage).

+
The starred form additionally supports the use of undeclared registers: it basically declares a registers upon its first usage.
- This will always be a \texttt{qubit} register; but if you use the corresponding option and the first usage is an \gate{init} command, you may overwrite this.
- Subcircuits always use the unstarred form.
-
- Additionally, if you refer to the index $i$ of a vector register of length $L < i$, this register will automatically be enlarged to $i \coloneq L$.

It is also possible to convert a scalar register into a vector register in this manner.

However, if you use an \emph{outer} range (i.e., a range between indices of registers with different names), the initial and final register of the range must be unique, i.e., either you omit the index (targeting the first or last register with the given name) or specify a single one.

\begin{warning}[Ranges and discontiguous registers]
Assume a configuration in which the vector register \yquant!a! begins with one qubit, then the single register \yquant!b! follows, and after that \yquant!a! is continued with another qubit.
-
+
The range \yquant!a-b! will target \yquant!a[0]! and \yquant!b[0]!, but not \yquant!a[1]!.
As \yquant!a! is used as the initial register in the range without an explicit index specification, \Yquant{} automatically translates this into \yquant!a[0]!, while \yquant!b!, being used as the final register, is automatically translated into the last register of name \yquant!b! (which here happens to be \yquant!b[0]!).
Ranges between different register names (outer ranges) are \emph{visual} ranges, i.e., they refer to the top\hyp to\hyp bottom order that is visible.
Consequently, the register \yquant!a[1]! is left out since it is visually below the others.
-
+
Likewise, the range \yquant!b-a! will target \yquant!b[0]! and \yquant!a[1]!.
-
+
Ranges within indices are \emph{logical} ranges.
Hence, \yquant!a!, \yquant!a[-]!, \yquant!a[0-]!, \yquant!a[-1]!, and \yquant!a[0-1]! are all equivalent: they all refer to the registers \yquant!a[0]! and \yquant!a[1]!, but never to \yquant!b!, regardless of any visual position.
\end{warning}
-
+
All that was said so far refers to the operation being carried out on each of the registers \emph{individually}, i.e., producing several copies of the operation.
- This is different from using the operation multiple times on the individual single registers only with regard to the vertical positioning: if specified as a register list with one operation, all copies of the operation will be aligned at the same vertical position (as if an \gate{align} command had been carried out before).
+ This is different from using the operation multiple times on the individual single registers only with regard to the horizontal positioning: if specified as a register list with one operation, all copies of the operation will be aligned at the same horizontal middle axis (for gates with the same width on each register, this is the same as issuing an \gate{align} command before performing the operations individually).

Typically, multi\hyp register operations should only be carried out on adjacent registers---but sometimes, one might want to carry out a multi\hyp qubit operation on a visually discontiguous set of registers (which, due to a particular quantum computer topology, might even be physically feasible).
- Since version 0.1.2, \Yquant{} supports these discontiguous operations explicitly (before, a single gate was drawn with all intermediate non\hyp affected register lines laying on top).
+ \compat{New in 0.1.2}\Yquant{} supports these discontiguous operations explicitly.
It will draw a \emph{main} part of the gate at the first contiguous slice of registers in the target list---you may select another register for this part by preceding the name or index with a star (which, contrary to the simplified grammar, may only occur \emph{once} in a target specification).
All other contiguous slices of target registers will be drawn in a \emph{subordinate style} for this gate.
Finally, all slices will be connected by a single vertical line with the style \style{/yquant/every multi line}.
- Subcircuits, supported as of version~0.2, will always span the full region from the first to the last register specified in a multi\hyp qubit gate.
- This is due to the fact that they may contain arbitrary ancilla registers which may be positioned somewhere in between the parts that actually constitute the subcircuit---so this whole region must not have wires of other registers crossing.

Every command may take one or multiple arguments.

\subsection{Controls}
Lots of gates may have controls, i.e., they are only to be executed if some other gate is set or unset.
The former case is called a \emph{positive control}, the latter one a \emph{negative control}.

The gate specification is followed by the list of target registers.

If there are no positive controls, the list may be empty or, together with the pipe, omitted.
Preceded by a tilde (``\yquant!~!''), the list of negative controls then follows; this mimics the syntax of many programming languages that denote logical negation by a tilde.

+ The value of this setting determines whether circuits drawn in a \Yquant{} environment in the current group will be drawn in a ``seamless'' state (hence, this style must be set \emph{before} the \Yquant{} environment is started).
+ The key \style{/yquant/operator/separation} will control the amount of padding with which a wire starts or ends before the first or after the last gate.
+ By turning on the seamless state, this padding is suppressed.
+ Using outputs or giving an initial value at the register declaration brings the corresponding padding back.
+ Usually, this setting is intended only for subcircuits.
+ Direct access is discouraged, as it will persist in subcircuits.
+ Only access it via \style{/yquant/operators/subcircuit/seamless}.
+ \end{option}
+
+ \begin{option}[New in 0.4]{every post measurement control}!indirect!
+ This style determines the default arrangement of measurements that are followed by positive controls.
+
+ The default option \texttt{indirect} will draw the measurement at the position where it is specified.
+ Any later use of a control will be at the position of the controlled gate.
+
+ The option \texttt{direct} will defer the measurement.
+ If later on, a controlled operation is used where the positive controls contain all of the targets of this measurement \emph{and} no other gate was executed meanwhile on any of the targets of this measurement, then the measurement gate will replace the corresponding positive control knobs (and might inherit \TikZ{} options of the embedding gate); otherwise, it will behave as if the \texttt{indirect} option had been specified.
+
+ Some care must be taken when gates are named that are affected by this option.
+ If the embedding gate is named, the positive controls that will be replaced by measurements are no longer available with the ``\texttt{p}''~suffix (but other positive controls will still be numbered as if all were).
+ Attach the name to the measurement in order to access it as if it were an ordinary gate; however, note that the name only becomes available after the later embedding gate was called.
+
+ Note that this setting affects all measurements that have a compatible shape; currently, this is only \gate{measure}.
+ While there is no technical difficulty in implementing the same behavior for \gate{dmeter}, its particular shape does not really suggest this use.
+ However, if you desire to do so, please file a feature request.

User\hyp defined gates are implemented via subcircuits; this style suppresses the box that surrounds the subcircuit and by default suppresses all register names.
This allows a seamless integration of the gate/subcircuit into the main circuit, without putting particular emphasis to the fact that what was defined as the custom gate indeed belongs together.

Note that in contrast to all other styles such as \style{/yquant/operators/every subcircuit} or \style{/yquant/this operator}, this style is only applied to the ``container'' node of the subcircuit, but not to the elements in the subcircuit themselves.
+ Also note that the box style by default contains an \texttt{inner xsep} that will be added as an inside padding.
+ This makes sense if your wires have labels so that these labels don't move too closely to the border of the box.

\section{Doing the impossible}\label{sec:tikz}
\Yquant{} will almost certainly never be able to do everything an author has in mind.
Sometimes, there is the need to draw something non\hyp standard, and this cannot be implemented in the \Yquant{} language.
However, since \Yquant{} is a layer on top of \TikZ, it should be very hard to find something (meaningful) that cannot be done by combining the power of both packages.
-
- Before or after any gate, you may interrupt the \Yquant{} instructions to perform arbitrary \TikZ{} path operations.
- After every such operation, \Yquant{} will automatically restart its parser so that you can fluently jump between \Yquant{} and \TikZ{} code.
- You can even interject arbitrary \TeX{} code (or, say, low\hyp level \pkg{pgf} commands); however, then, \Yquant{} is not able to restart its parser.
- For this reason, after the last command in a block of \TeX{} commands, you must issue \tex!\yquant!, which then re\hyp enables the \Yquant{} language.
-
- The feature to perform arbitrary \TikZ{} operations is powerful in itself, but would be of limited use were there no way to access the elements in the quantum circuit.
- \Yquant{} provides a global attribute \texttt{name} that can be assigned to every gate.
- All quantum operations are in fact \TikZ{} nodes, and the name you give to them then becomes a \TikZ{} name, which you can easily reference to get the coordinates of a particular operator.
- Note that the name you specify is only available if a single register is targeted.
- The name is suffixed by \tex!-\idx!, where \tex!\idx! refers to the (zero\hyp based) index of the operation ordered from top to bottom (i.e., if an operator acts on two qubits and should be named \texttt{op}, the topmost operator will be available as \texttt{op-0} and the second as \texttt{op-1}).
- Multiple slices in a discontiguous multi\hyp register are additionally suffixed by \texttt{-s\textit{<slice index>}}.
- All controls are also named, suffixed by \tex!-p\idx! or \tex!-n\idx! for positive and negative controls (i.e., the topmost positive control of the previous operator will be available as \texttt{op-p0}).
- Counters for target registers, positive, and negative controls are all independent.
- Finally, you can even access names within a subcircuit, provided you give a name to the subcircuit.
- All nodes in the subcircuit will then have the name \texttt{\textit{<subcircuit name>}-\textit{<name specified in the subcircuits>}}.
- For nested subcircuits, you will get multiple prefixes.
-
- All \Yquant{} shapes have the anchors available you would typically expect from a \TikZ{} shape of the given outline.
- Before version~0.1.2, \Yquant{} shapes needed to provide a \texttt{circuit} anchor and projection anchors.
- These were removed in version~0.1.2 in favor of the common \texttt{center} anchor and clipping paths.
- The latter is a \Yquant{} extension to \TikZ{} shapes: it is an additional path that must be declared for a given shape.
- This path has to provide the ``clipping outline,'' i.e., anything that should not contain register or control lines.
- There may be a difference between horizontal and vertical clipping outlines.
- To understand clipping paths, \Yquant's drawing pipeline needs to be explained.
- \begin{itemize}
- \item In a first run---this is what happens directly at the position where you type the gate command---\Yquant{} will ``virtually'' draw the gates in order to determine their dimensions and calculate register heights.
- The actual drawing commands are written to a macro (this is the cause that some macros must be preceded by \tex!\protect! if used in a gate \texttt{value}).
- \item When \tex!\end{yquant}! is encountered, the actual drawing commands are executed.
- \item Unless the operation changes the wire type or style, do the following (first two items for every register at which an operator node has to be created).
- \begin{itemize}
- \item Create the operator node at the appropriate position.
- \item Call \tex!\pgfshapeclippath! on the newly created node.
- This will first determine whether the node was stroked; if not, \tex!\pgflinewidth! is set to zero.
- Then, it will call the horizontal clipping path, which is supposed to create some soft path commands.
- Those soft path commands are collected in a macro on a per\hyp register basis and the soft path is cleared.
- The same happens for the vertical clipping path, which is collected in a macro on a per\hyp operation basis.
- \item If control lines or multi lines are to be drawn, the vertical clipping path commands are now executed and installed as an inverted\footnote{Inverting the clipping has two consequences: First, the region of inversion in vertical direction is given by the width of the operators. The line cannot be wider than the operator. Second, if you specify a register multiple times, whether as target, control, or mixed, funny effects can be expected, as the clipping region is inverted multiple times. Note that using a register more than once is always an error, but \Yquant{} does not check for it due to the high overhead.} clipping path.
- \item Control lines and multi lines are drawn (in this order) from one to the next \texttt{center} anchor.
- Due to the clipping commands, this will create a perfect connection with the shape of the gate, but even transparent gates are possible without the lines being visible.
- \end{itemize}
- \item If the operation changes the wire type or style, or if there is no operation left on this register, the following is done.
- \begin{itemize}
- \item Load the clipping paths accumulated for all the gates acting on this register and install the inverted clipping.
- \item Draw the wire as one continuous line from where the last wire ended (or the beginning of the circuit) to the center of the last gate, or to the common end position for all wires of the circuit.
- \item Remove the clipping paths stored so far on this register, apart from the clipping on the last gate (which will be needed again if this was not the end of the circuit).
- \end{itemize}

+ \subsection{Mixing \texorpdfstring{\Yquant}{yquant} and \texorpdfstring{\TikZ}{TikZ} code}
+ Before or after any gate, you may interrupt the \Yquant{} instructions to perform arbitrary \TikZ{} path operations.
+ After every such operation, \Yquant{} will automatically restart its parser so that you can fluently jump between \Yquant{} and \TikZ{} code.

+ \subsection{Accessing gates in \texorpdfstring{\TikZ}{TikZ}}
+ The feature to perform arbitrary \TikZ{} operations is powerful in itself, but would be of limited use were there no way to access the elements in the quantum circuit.
+ \Yquant{} provides a global attribute \texttt{name} that can be assigned to every gate.
+ All quantum operations are in fact \TikZ{} nodes, and the name you give to them then becomes a \TikZ{} name, which you can easily reference to get the coordinates of a particular operator.

+ All nodes in the subcircuit will then have the name \texttt{\textit{<subcircuit name>}-\textit{<name specified in the subcircuits>}}.
+ For nested subcircuits, you will get multiple prefixes.
+
+ \subsection{Shapes and the drawing pipeline}
+ All \Yquant{} shapes have the anchors available you would typically expect from a \TikZ{} shape of the given outline.
+ The \texttt{center} anchor will be aligned to the wire.
+ \compat{Changed in 0.1.2}In addition to the normal paths implemented by \TikZ{} shapes, those fit for \Yquant{} must additionally implement clipping paths, a \Yquant{} addition to \TikZ{} shapes.
+ Such a path has to provide the ``clipping outline,'' i.e., anything that should not contain register or control lines.
+ There may be a difference between horizontal and vertical clipping outlines.
+ To understand clipping paths, \Yquant's drawing pipeline needs to be explained.
+ \begin{itemize}
+ \item In a first run---this is what happens directly at the position where you type the gate command---\Yquant{} will ``virtually'' draw the gates in order to determine their dimensions and calculate register heights.
+ The actual drawing commands are written to a macro (this is the cause that some macros must be preceded by \tex!\protect! if used in a gate \texttt{value}---in fact, if multiple registers are targeted in one gate, the style and values required for this gate are only stored once, so that for example \tex!\idx! is a \tex!\protected! macro until the very end).
+ \item \compat{New in 0.4}Deferred gates (measurements that may replace future control knobs) are stored temporarily and queried when the next gate is executed or at the end of the circuit.
+ The corresponding commands---either re\hyp inserting if they must appear at their original position or substituting the controls---are inserted appropriately.
+ \item When \tex!\end{yquant}! is encountered, the vertical positions are determined and the actual drawing commands are executed.
+ \item Unless the operation changes the wire type or style, do the following (first two items for every register at which an operator node has to be created).
+ \begin{itemize}
+ \item Create the operator node at the appropriate position.
+ \item Call \tex!\pgfshapeclippath! on the newly created node.
+ This will first determine whether the node was stroked; if not, \tex!\pgflinewidth! is set to zero.

+ The same happens for the vertical clipping path, which is collected in a macro on a per\hyp operation basis.
+ \item If control lines or multi lines are to be drawn, the vertical clipping path commands are now executed and installed as an inverted\footnote{Inverting the clipping means that instead of drawing only \emph{within} the clipping path (which corresponds to the gates), we only draw \emph{outside}. However, as there is no direct support for this, we invert by exploiting the even\hyp odd rule. If you specify a register multiple times, whether as target, control, or mixed, funny effects can be expected, as the clipping region is inverted multiple times. Note that using a register more than once is always an error, but \Yquant{} does not check for it due to the high overhead.} clipping.
+ \item Control lines and multi lines are drawn (in this order) from one to the next \texttt{center} anchor.
+ Due to the clipping commands, this will create a perfect connection with the shape of the gate, but even transparent gates are possible without the lines being visible.
+ \end{itemize}
+ \item If the operation changes the wire type or style, or if there is no operation left on this register, the following is done.
+ \begin{itemize}
+ \item Load the clipping paths accumulated for all the gates acting on this register and install the inverted clipping.
+ \item Draw the wire as one continuous line from where the last wire ended (or the beginning of the circuit) to the center of the last gate, or to the common end position for all wires of the circuit.
+ \item Remove the clipping paths stored so far on this register, apart from the clipping on the last gate (which will be needed again if this was not the end of the circuit).
+ \end{itemize}
+ \end{itemize}
+
+ \subsection{Overwriting the height and depth calculation}
+ \Yquant{} automatically takes care of calculating the height and depth of all registers, so that their final vertical positions are chosen without overlap.
+ This is almost always advisable, but it has some weaknesses:
+ \begin{itemize}
+ \item If you specify a multi\hyp register gate, say, extending for three registers and this requires a certain height and depth, where should this be accounted for?
+ \compat{New in 0.4}\Yquant{} is able to handle these situations by first determining all heights and depths that can safely be attributed to individual registers.
+ After that, it checks for all multi\hyp register gates: Is the space from the top of the first to the bottom of the last register enough to hold the multi\hyp qubit gate?
+ If not, it evenly distributes the additional required space to all registers that are visually within the range of this multi\hyp register.
+
+ This will fail to produce good results (hopefully) only in two cases:
+ \begin{itemize}
+ \item If you place \texttt{label}s on the gate, those are outside of the gate---and typically, either below or above.
+ Hence, the additional extent stemming from them should \emph{not} be equally distributed among all registers, but either to the height of the first or the depth of the last one.
+ Currently, \Yquant{} is unable to detect this (and, considering the fact that you can place \texttt{label}s at any angle, this is not an easy problem to solve except for special cases).
+ \item If you make use of a discontiguous \gate{init} gate with a large vertical extent, \Yquant{} will correctly allocate space as if the gate's content were placed in the vertical center.
+ However, if there is no way to put the arch of the brace at the middle, as the register at this position is excluded from the gate, the content will be shifted---but only after calculating the extent.
+ Hence, the automatically calculated vertical positions will be unsuitable.
+ \end{itemize}
+ \item Sometimes, there is more space available than \Yquant{} thinks because you already discarded some wire.
+ \Yquant{} does not keep track of whether the wires below or above a gate are actually visible at this position---which is not even be known at the time the gate command is issued, as horizontal positions are determined only in the drawing stage.
+ Hence, you may choose to draw ``within'' the other, invisible wire.
+ \end{itemize}
+
+ \compat{New in 0.4}In these certain special cases, you may want to turn off the automatic calculation for one particular gate.
+ Note that you may then, depending on the situation, obtain results with overlapping gates.
+ You can use the keys \style{/yquant/register/minimum height} and \style{/yquant/register/minimum depth} when declaring the relevant register to manually specify a larger desired value, but you have to experiment with regard to what this value is.
+
+ The global attribute \texttt{overlay} (conveniently overshadowing \TikZ's \texttt{overlay} key, which should not be used for gates) can take the values
+ \begin{itemize}
+ \item \texttt{true} (default if no value given, combines \texttt{multi}, \texttt{height}, and \texttt{depth}),
+ \item \texttt{multi} (short \texttt{m}),
+ \item \texttt{height} (short \texttt{ht}, \texttt{h}),
+ \item \texttt{depth} (short \texttt{dp}, \texttt{d}),
+ \item \texttt{single} (short \texttt{s}, combines \texttt{height} and \texttt{depth}), and
+ \item \texttt{false} (useless, default if attribute not given).
+ \end{itemize}
+ It disables the calculation of the selected vertical extent for this particular gate.
+ (In fact, \texttt{multi}, \texttt{height}, \texttt{depth}, and \texttt{single} are subkeys that accept boolean values.)

Usually, this would be sufficient to put the \gate{cnot} and the \gate{slash} gate directly under each other, as it is in the \pkg{qasm} example.
However, the \gate{slash} gate is special in that it does not need horizontal space and is put with only half of the usual operator separation into the circuit (for this reason, it can be put at the beginning of a wire without creating weird shifts with respect to the ``unslashed'' registers---it is put in the initial line that every wire even without an operation has).
Hence, you should normally only use the \gate{slash} gate as the very first gate in a circuit.
- It is not possible to construct the exact same appearance as in the \pkg{qasm} example.

- Here, we chose to realize the equality using two \tex!tikzpicture!s with appropriately set baselines.
-
- If mangling with the baselines becomes problematic, a different approach would be to use an outer \tex!tikzpicture! with three nodes (left circuit, equals, right circuit); but the circuits themselves are \tex!tikzpictures! again, and nesting those is dangerous (but may work).
- Instead they could have been put into \tex!\savebox!es and just used.
-
- Finally, using nested \tex!tikzpictures! for the outer nodes is not really necessary.
- Not using nodes but putting the two \tex!yquant*! environments in a \TikZ{} \tex!scope! with \texttt{shift} transformation would have also worked.
+ The best way to realize circuit equalities is with the help of \texttt{frameless} subcircuits.
+ The \texttt{[frameless]} attribute can either be specified on each subcircuit individually or, as done here, globally via the corresponding style.
+ In this way, we can specify all subcircuits individually.
+ All wires that are identical in the circuits must be outer wires; but in fact, we do not want them to be visible outside of the subcircuits.
+ Consequently, we initialize them in the outer circuit as \gate{nobit}s, declare them with the \texttt{[out]} attribute, and discard them right after the subcircuit.
+ It is important not to discard them within the subcircuit, as the wires would then not extend to the same horizontal final position.
+ The equality sign is realized very easily by means of a \gate{box} gate that spans all registers and from which we remove the border.

+ The example demonstrates how to put a description next to a gate.

+ Using the \TikZ{} library \texttt{quotes}, the label is most easily specified.
+ Since the label is not part of the valid arguments and also cannot be found in the \texttt{/yquant} path, it is automatically passed to \style{/yquant/operator style}.
+
+ To enclose a part of the circuit by a rectangle, we use a subcircuit.
+ We define the incoming \gate{qubit}s in the outer circuit, they will have the default attribute \texttt{[inout]}; the syndrome registers, which are created only in the subcircuit enter as \gate{nobit}s and consequently have the \texttt{[out]} attribute.
+ It is important to note that both the \texttt{dashed} style as well as the \texttt{label} (here with quoted syntax) are specified only inside \style{/yquant/this subcircuit box style}.
+ This ensures that they are not also attached to every single gate in the subcircuit.
+
+ Then we see how to apply an operation to multiple registers in parallel while using the \tex!\idx! macro to still give them a different text.
+ Since \tex!\idx! gives a numerical index (zero\hyp based), we exploit the ASCII code (actually, this document is compiled in Unicode mode...) to turn this into a letter.
+
+ Note that it could have become necessary to pass the \texttt{overlay} attribute to the recovery gate, as it is a multi\hyp register gate with a \texttt{label}, meaning that \Yquant{} cannot reliably distribute its total vertical extent over its constituent registers.
+ However, as the $\symcal R$ together with the label in total were not higher than the three\hyp qubit gate would have been anyway, this was not necessary here.
+ In generally, don't use \texttt{overlay} unless necessary; maybe a future version will even be able to handle the more difficult cases better.
+
+ Finally, we will give a similar circuit by using the \TikZ{} interface instead of subcircuits, this time also showing how we can change the shape of the measurement gate to one as in the \pkg{qcircuit} manual:

- Here, we also make use of the \texttt{moveto} decoration transformation that comes with \Yquant{} and that allows to enlarge the braces slightly for a good overall appearance.
- Finally, as $y$ has a much smaller height than $y \oplus f(x)$, we make sure this does not affect the vertical positioning; and also, as $x$ has no ascender, we need to slightly position it off\hyp mid for a good look.
+ We use quite some tricks to achieve such a layout.
+ We use a subcircuit as a container and \gate{inspect} gates to indicate the inputs and output states accurately.
+ As those are ordinary gates, we reset \style{/yquant/operator/minimum width}, so that the ``$y$'' indication is not too long.
+ Additionally, they are usually meant to be used within a circuit, i.e., they have an additional margin denoted by the \texttt{outer xsep}, which we also remove.
+ Then, within the subcircuit, we reset the \style{/yquant/operator/separation}, which would insert additional whitespace at the beginning.
+ It is important to do this within the subcircuit and not as an attribute; else, we would also remove the outer lines going into the subcircuit.
+
+ Initial or final \gate{inspect} gates without a brace do not really need the separation between brace tip and text (\texttt{inner xsep}), so we also remove it.
+ The output gates should have their braces and separations at the other side, which corresponds to changing their shape from \texttt{yquant-output} to \texttt{yquant-init} and mirroring the decoration (as in \style{/yquant/every label}).
+ To get the desired right\hyp alignment, we hand\hyp tailor an \tex!\hskip! that enlarges the upper output label---automatic alignments would not work here: putting the two \gate{inspect}s together with a case distinction on \tex!\idx! would center them; using \gate{output}s would left\hyp align them.
+
+ Finally, we have to deal with the caption of the gate, which should be absolutely centered with respect to the subcircuit and not have any influence on the spacing---so we just insert it retrospectively as an ordinary \TikZ{} node.
+
+ Also note the use of \gate{discard} and \gate{settype} since we needed wires before and after the subcircuit, which must match the inner wires in type, but we actually do not want to have inner wires.

Note that whatever you write between \tex!\begin{qasm}! and \tex!\end{qasm}! is essentially treated as verbatim; only where the specification says so (in the definition of a new gate and in the optional third command to the register definition), it is interpreted as \TeX{} markup.
- Consequently, in \pkg{beamer}, any frame containing these environments must be given the \texttt{verbatim} option.

+ Consequently, in \pkg{beamer}, any frame containing these environments must be given the \texttt{fragile} option.

\subsubsection{Configuration}
Loading the \pkg{qasm} language interpreter will define several new configuration keys.
For all the gates, it will use the keys defined in \cref{sec:config}, and it additionally provides the following:
-
+
\begin{option}{operators/every s}!/yquant/operators/every box!
This style is installed for every \texttt{s} operator.
\end{option}
-
+
\begin{option}{operators/every t}!/yquant/operators/every box!
This style is installed for every \texttt{t} operator.
\end{option}
-
+
\begin{option}{operators/every utwo}!/yquant/operators/every box!
This style is installed for every \texttt{Utwo} operator.
\end{option}
-
+
\begin{option*}{qasm}{zero}!\qasm at ket0!
The content of this macro is used as the initialization content whenever the \texttt{zero} gate is invoked.
\end{option*}
-
+
\begin{option*}{qasm}{register/default qubit name}!\qasm at ket{#1}!
This macro is invoked with a single parameter (the name of a qubit register) and gives back what is printed as the name of the register (will be in math mode automatically).
\end{option*}
-
+
\begin{option*}{qasm}{register/default qubit name value}!\qasm at ket{#1} = \qasm at ket{#2}!
This macro is invoked with two parameters (the name of a qubit register and its initial value) and gives back what is printed as the name of the register (will be in math mode automatically).
\end{option*}
-
+
\subsubsection{Examples}
- The unaltered\footnote{Only in \texttt{test14.qasm}, \tex!\cal! was replaced by \tex!\symcal!---and this is only necessary as this manual was set with \pkg{unicode-math}. In traditional mode, even this would not be necessary.} \texttt{.qasm} files provided from \href{https://www.media.mit.edu/quanta/qasm2circ/}{the \texttt{qasm2circ} page} were stored in the subfolder \texttt{qasm} relative to this manual's \TeX{} file.

In principle, \Yquant's approach could allow for a simple key switch that changes horizontal to vertical.

\section{Changelog}
\subsection*{2020-03-15: Version 0.1}
Initial release
-
+
\subsection*{2020-03-22: Version 0.1.1}
Complete rewrite of the register name parser.
\Yquant{} now understands comma\hyp separated lists and ranges in indices, and also is far more tolerant with respect to whitespaces. \\
\Yquant{} now also supports non\hyp contiguous vector registers and allows to add new registers into an already existing vector that is not the last register, and also in the unstarred mode.
-
+
\subsection*{2020-04-11: Version 0.1.2}
Introduce \gate{setstyle} and \gate{addstyle} pseudo\hyp gates that allow to style individual wires; rename \gate{setwire} to \gate{settype} (the old name is still available and shows a deprecation warning). \\
Complete rewrite of the way \Yquant{} draws wires; projection anchors are removed in favor of clipping paths.
@@ -3047,24 +3390,42 @@
\Yquant{} now also properly draws non\hyp contiguous multi\hyp qubit operations. \\
New gate: \gate{correlate}.
Various bug fixes.
-
+
\subsection*{2020-06-02: Version 0.2}
Introduce \gate{subcircuit}; required rewriting how \Yquant{} internally positions vertically.
Provide simple macros to load circuits (or parts) from a file and to declare own custom gates.
-
+
\subsection*{2020-06-07: Version 0.2.1}
Introduce a macro to declare a lightweight custom gate, which is only a single box with custom content.
-
+
\subsection*{2020-06-13: Version 0.3}
Introduce support for the \pkg{qasm} language.
-
+
\subsection*{2020-07-11: Version 0.3.1}
Add legacy support for very old \TikZ{} versions such as the one used on the arXiv.
-
+
\subsection*{2020-08-24: Version 0.3.2}
Fix \href{https://github.com/projekter/yquant/issues/5}{\#5}: Can't draw circuits with more than 9 qubits.
-
+
\subsection*{2020-10-27: Version 0.3.3}
Fix \href{https://github.com/projekter/yquant/issues/6}{\#6}: shorten doesn't work for 2-qubit barriers. This fixes a bug in how the \texttt{shorten} keyword worked on \gate{barrier}s, which may require re\hyp assessing your chosen values.
+
+ \subsection*{2021-02-21: Version 0.4a}
+ Lots of internal fixes, most notably vertical alignment with subcircuits. \\
+ Introduce capability to perform vertical alignment with multi\hyp register gates. \\
+ Dramatic changes under the hood regarding horizontal positioning, which is now only determined in the drawing stage; this paves the way for delayed gates, which are planned for 0.4.
+ Also changes in the gate declaration interface. \\
+ Introduce compatibility layer, so that layout\hyp breaking changes will not become effective unless explicitly requested. \\
+ Separate register height into a height and depth key. \\
+ Introduce \texttt{overlay} key to disable height caluclation selectively. \\
+ Change register style declaration, so that this is now always equivalent to creating an unnamed register followed by an \gate{init} gate with the given text.
+ Note: This may be a \textbf{breaking change} that cannot be compatibility\hyp protected---if you used \TeX{} conditionals involving \tex!\idx! for creation labels of registers, you will now need to either \tex!\protect! them all or just capitalize their first letter (which corresponds to auto\hyp\tex!protect!ed versions for \texttt{compat} at least \texttt{0.4}). \\
+ Now use nodes for \gate{init} and \gate{output} gates. \\
+ Change behavior of \gate{hspace} and \gate{align}: Now also extend if the wire is discarded afterwards. \\
+ Introduce the commands \tex!\Ifnum!, \tex!\Ifcase!, \tex!\Or!, \tex!\Else!, \tex!\Fi!, \tex!\Unless! and \tex!\The! available for use within gates that behave like auto\hyp\tex!\protect!ed versions of their plain \TeX{} equivalents.
+
+ \subsection*{2021-03-27: Version 0.4}
+ New gate: \gate{inspect}. Various bug fixes. \\
+ Introduce the \texttt{direct control} feature: \gate{measure} gates can now substitute positive controls of future gates.

- % We know the heights of most gates, but subcircuits are tricky. Since the position of their inner wires depends on the heights of the outer wires, we could not make any assumption about their heights yet. So we now need multiple iterations: First, we fix the positions of our own wires preliminarily. Then, we iterate through all subcircuits at the first level, place their wires appropriately and try to align input and output. In doing so, we recognize when there's not enough space at an outer wire. If this is the case, we enlarge the outer wire's height appropriately and restart alignment from the outmost level. If everything is proper, we start aligning at the next level.

We expect that for most of all multi gates, we already have enough space. But sometimes, this may not be the case, so we need to increase overall spacing and re-evaluate all spacing. In order to get a proper balanced layout, we start with the largest enlargement that is required. Every enlargement step will equally distribute the registers in between. Starting with the largest one, this is likely to also solve issues with smaller ones.
