It is possible to mix single- and multi\hyp register operations arbitrarily.
In an index list, you may also choose to surround only certain indices with parenthesis, provided the whole register is not already a multi\hyp register.
\begin{warning}
- Note that some gates, such as the \gate{swap} gate, always require multi\hyp register operations with a fixed number of constituents; others, such as the \gate{slash} pseudo\hyp gate always require single\hyp register operations.
- Again others are completely flexible.
+ Note that some gates, such as the \gate{swap} gate, always require (semantically, not grammatically) multi\hyp register operations.
+ Since version 0.1.2, the number of constituents is no longer fixed; while a \gate{swap} gate with more than two targets is no longer well\hyp defined, other registers such as \gate{zz} may still be useful.
\Yquant{} will prevent you from using a gate in a multi\hyp qubit setting when it may only be used for single registers.
- All other types of validity checks are up to the user.
\end{warning}
+ 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).
+ 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}.
+ \begin{warning}[Discontiguous targets and control lines]
+ A control line extends from the very first to the very last affected register in an operation.
+ A sub\hyp gate line that is used for discontiguous registers will only span the range of a multi\hyp register.
+ This distinction becomes crucial if you want to carry out a \emph{controlled} operation on more than one multi\hyp register, where at least one is discontiguous.
+ Without the controls, the separate multi\hyp registers could be identified, since no connecting vertical line extends between them (unless, which you should strictly avoid, they are intertwined).
+ However, with the controls, the control line will make it hard (for some gates, impossible) to visually distinguish the connected parts.
+ \Yquant{} will kindly provide a warning in this case.
+ You may choose to suppress this warning using the boolean key \style{/yquant/operator/multi warning}.
+ \end{warning}
+ \begin{warning}
+ There is no established style for discontiguous gates.
+ Note that at the moment, main and subordinate style coincide for all gates except for the \gate{measure} gate with a value.
+ In order to still make it possible to visually distinguish discontiguous multi\hyp register gates operating on slices of a single register from just a bunch of single\hyp register gates that are executed in a parallel manner, if controls are present, \Yquant's default vertical line style for the former case is a wavy line instead of a straight one.
+ Still, the meaning of this should probably be explained.

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.
All \Yquant{} shapes have the anchors available you would typically expect from a \TikZ{} shape of the given outline.
- Additionally, \Yquant{} shapes will have an anchor \texttt{circuit}; and apart from border anchors, they also implement \emph{projection anchors}.
- As with the former, you will need low\hyp level macros to access these anchors, which are \tex!\pgfpointshapexproj! and \tex!\pgfpointshapeyproj!.
- They will expect the name of the node as first argument and a \pkg{pgf} point as second argument.
- This point will be projected onto the shape in horizontal or vertical direction.
- These special types of anchors are internally used to determine where the intersection of wire and shape is located.
+ 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}
