+Standard gate commands will typically work well with the alternate option for bundled quantum wires.

-\subsubsection{Perfecting Vertical Alignment}
-
-If you want total control over vertical alignment between several different circuits, the trick is to use the \verb!baseline! key. All the baselines of different items are placed on the same level. This is particularly helpful if you give certain wires in the circuit a name, and that will let you place the baseline directly on a level with that wire.
-
-To name a wire as `name', place an \verb!\alias{name}! command in any cell which is either empty, or contains a \verb!\qw!, \verb!\cw! or \verb!\push! \emph{only}, and place it before that command\footnote{Alternatively, for any node that accepts tikz styling parameters directly as an option, passing the option \texttt{alias=name} should do.}. That lets you align circuit identities such as
+Alternatively, you can use a \texttt{midstick} command, which is a bit like \texttt{rstick} or \texttt{lstick}. By default, it places braces both before and after, but these can be replaced using the optional argument \texttt{brackets=none|left|right|both}. This is typically the simplest options. Thus,
\begin{Code}
-$$
-\begin{quantikz}[baseline=(W.base)]
-\lstick{\ket{0}} & \qw & \ctrl{1} & \qw \\
-& \gate{H} & \targ{} & \alias{W} \qw
+\begin{center}

+& \qw & \ctrl{1} & \midstick[2,brackets=none]{=}\qw& \ctrl{1} & \gate{Z} & \qw \\

\end{quantikz}

-\begin{quantikz}[baseline=(W.base)]

\end{lstlisting}
\end{Code}
-This has aligned the bottom wire of the first circuit with the wire in the second circuit, making the correspondence more obvious. However, the $\equiv$ sign is now in the wrong place, with its baseline placed at the same point as the baseline of the circuits. We can fix this with a vertical shift of the two diagrams. We demonstrate two different ways of achieving the same effect (the only important feature is that both diagrams have the same shift).
+Another example that doesn't remove the braces:

-If you have an even number if wires, you might choose to calculate the centre of the circuit from \verb!current bounding box.center!, or you could perform a calculation to average the position of two wires. This calculation can then be adjusted to take into account the desire to vertically align on the centre of an equals sign rather than the baseline (which is below the bottom of the equals)
+ \subsubsection{Perfecting Vertical Alignment}
+Sometimes when you're typesetting circuit identities as multiple separate circuits, the vertical alignment of the equals sign doesn't appear quite right (and can really niggle). Here, for example, the equals seems a bit high:

+\lstick{\ket{0}} & \targ{} & \ctrl{-1} & \qw
\end{quantikz}
-=\begin{quantikz}[baseline={($(W.base)!.5!(W2.base) - height("$\vcenter{}$")*(0,1pt)$)}]

+\end{Code}
+To that end, we have added the key \texttt{align equals at=} option for the tikzcd and quantikz environments. This specifies which wire should be align with the equals sign. You can even use a non-integer. For instance, 2.5 will set it half way between wires 2 and 3.

+\item If you're using a circuit diagram inside an \texttt{align} environment, the \texttt{tikzcd} environment works better than \texttt{quantikz}. You may also need to use the ampersand replacement strategy.
\item If you have a \verb!\cwbend! in the bottom right cell of the matrix, sometimes you get an error (I have no understanding of why). Add an extra \& after, and all seems to be well.
\item If you're using transparency, and the width of gates seems to be greater than you expected, it may be worthwhile removing the .aux file and recompiling. If your tex editor isn't good at resetting the .aux file, the system may be remembering older widths.
\item The code provides definitions for \verb!\bra!, \verb!\ket!, \verb!\proj!, \verb!\braket!. If you don't like them, just define your own versions \emph{before} you load the quantikz library.
+\item Package load order: I've had reports that if you load certain packages in the wrong order it can create weird errors. For example, if you load the package cleveref after quantikz, and then use a split environment, it can lead to the error ``Only one \# is allowed per tab.''. Change the load order and it goes away. I have no idea why this happens.

+%This is the quantikz library for typesetting quantum circuits using LaTeX/Tikz. version 0.9.6

% Usage is at your own risk.
+%version 0.9.6:
+% changed packaging so there isn't a compile warning any more
+% modified the meter command so that \meter[draw=blue]{} colours everything blue, not just outline.
+% added trash command
+% added \ctrlbundle command so that \ctrl works well with \qwbundle[alternate]. If you supple \ctrlbundle[2]{}, then the bundle only contains 2 wires instead of the default of 3
+% \qwbundle[alternate] now also works with the parameter \qwbundle[alternate=2] to only have 2 wires in the bundle.
+% added \midstick. Works a bit like rstick and lstick, but reserves space for the text. Can choose to have brackets=none|left|right|both (default is both). Gives better method for circuit identities and other things.
+% added "align equals at" key for setting circuit identities (specifies wire number that should line up with equals. can be non-integer)
+% added makeebit command. accepts one parameter which is the text. Haven't got tyling and different angles of the split working yet.
+% added bundle option to supplement nwires and cwires.
+% fixed bug where you couldn't put a wire command after the declaration of a multi-qubit gate command.
%version 0.9.5:
% fixed bug which meant multi-wire gates didn't work outside of an environment such as center.
