Estou tentando enviar um tex para um circuito quântico usando TikZ. Eu sei que quero adicionar um medidor de medição como aqui no lado direito:
Qualquer ajuda será apreciada.
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,decorations.pathreplacing}
\begin{document}
\begin{tikzpicture}
\draw[thick,decorate,decoration={brace},xshift=-4pt,yshift=0pt]
(0,0) -- (0,1) node [black,midway,xshift=-1cm] {Input $\rho^{(i)}$};
\draw[thick,->] (0,1)--node[midway,above]{\footnotesize System $A$}(2,1);
\draw[thick,->] (0,0)--node[midway,above]{\footnotesize System $B$}(2,0);
\draw[thick] (2,-0.5) rectangle (3,1.5) node [pos=.5]{$U_\varepsilon$};
\draw[thick,->] (3,1)--(6,1);
\draw[thick,->] (3,0)--(4,0);
\draw[thick] (4,-0.5) rectangle (5,0.5) node[pos=.5]{$T$};
\draw[thick,->] (5,0)--(6,0);
\draw[thick,decorate,decoration={brace,mirror},xshift=4pt,yshift=0pt]
(6,0) -- (6,1) node [black,midway,xshift=1.35cm] {Output $\rho^{(i+1)}$};
\draw[thick,->,dashed,rounded corners] (7,0.2)--(7,-1)--node[midway,below]
{as long as $i+1<n$}(-1.5,-1)--(-1.5,0.2);
\end{tikzpicture}
\end{document}

No início, presumi que você estava usando o Maybe circuitikz, um pacote que talvez você devesse examinar, mas depois postou seu código. No entanto, aqui está uma solução que pode ser usada com ambas as abordagens:
(Como não sei onde você deseja colocar o medidor, substituí o nó T na sua foto.)
\documentclass[border=5mm,tikz]{standalone}
\usepackage{circuitikz}
\usetikzlibrary{arrows,decorations.pathreplacing}
\begin{document}
\tikzset{meter/.append style={draw, inner sep=10, rectangle, font=\vphantom{A}, minimum width=30, line width=.8,
path picture={\draw[black] ([shift={(.1,.3)}]path picture bounding box.south west) to[bend left=50] ([shift={(-.1,.3)}]path picture bounding box.south east);\draw[black,-latex] ([shift={(0,.1)}]path picture bounding box.south) -- ([shift={(.3,-.1)}]path picture bounding box.north);}}}
\begin{circuitikz}
\node[meter] (meter) at (0,0) {};
\draw (-4,0) to[twoport,t=$H$] (meter.west);
\draw(meter.10) -- ++(1,0);
\draw(meter.-10) -- ++(1,0);
\end{circuitikz}
\begin{tikzpicture}
\draw[thick,decorate,decoration={brace},xshift=-4pt,yshift=0pt]
(0,0) -- (0,1) node [black,midway,xshift=-1cm] {Input $\rho^{(i)}$};
\draw[thick,->] (0,1)--node[midway,above]{\footnotesize System $A$}(2,1);
\draw[thick,->] (0,0)--node[midway,above]{\footnotesize System $B$}(2,0);
\draw[thick] (2,-0.5) rectangle (3,1.5) node [pos=.5]{$U_\varepsilon$};
\draw[thick,->] (3,1)--(6,1);
\node[meter] (meter) at (4.5,0) {};
\draw[thick,->] (3,0)--(meter);
\draw[thick,->] (meter)--(6,0);
\draw[thick,decorate,decoration={brace,mirror},xshift=4pt,yshift=0pt]
(6,0) -- (6,1) node [black,midway,xshift=1.35cm] {Output $\rho^{(i+1)}$};
\draw[thick,->,dashed,rounded corners] (7,0.2)--(7,-1)--node[midway,below]
{as long as $i+1<n$}(-1.5,-1)--(-1.5,0.2);
\end{tikzpicture}
\end{document}
