Todo: * Optimize printing of large circuits. * Get this to work with single gates. * Do a better job checking the form of circuits to make sure it is a Mul of Gates. * Get multi-target gates plotting. * Get initial and final states to plot. * Get measurements to plot. Might need to rethink measurement as a gate issue. * Get scale and figsize to be handled in a better way. * Write some tests/examples! ) annotations)Mul) import_module)Gate OneQubitGateCGateCGateS) CircuitPlot circuit_plotlabellerMzMxCreateOneQubitGate CreateCGatenumpy matplotlibfromlistpyplot) import_kwargscatchc@seZdZUdZdZdZdZdZdZdZ gZ de d<iZ de d <d Z d d Zd dZddZddZddZddZddZddZddZddZdd Zd!d"Zd#d$Zd%d&Zd'd(Zd)d*Zd+S),r z$A class for managing a circuit plot.g?g4@g?g333333?z list[str]labelszdict[str, str]inits?cKs`trtstd||_t|jj|_||_||| | | | | dS)Nz"numpy or matplotlib not available.)npr ImportErrorcircuitlenargsngatesnqubitsupdate _create_grid_create_figure _plot_wires _plot_gates_finish)selfcrkwargsr)Y/var/www/html/zoom/venv/lib/python3.10/site-packages/sympy/physics/quantum/circuitplot.py__init__<s  zCircuitPlot.__init__cCs|j|dS)z'Load the kwargs into the instance dict.N)__dict__r )r&r(r)r)r*r IszCircuitPlot.updatecCsF|j}tjd|j||td}tjd|j||td}||_||_dS)zCreate the grid of wires.g)dtypeN)scalerarangerfloatr _wire_grid _gate_grid)r&r. wire_grid gate_gridr)r)r*r!Ms  zCircuitPlot._create_gridcCstj|j|j|j|jfddd|_|jjddddd}|d|j}||j d||j d|| |j d||j d|| d ||_ d S) z"Create the main matplotlib figure.w)figsize facecolor edgecolorT)frameonrrequalN)rfigurerr.r_figure add_subplot set_axis_offset_xlimr2set_ylimr1 set_aspect_axes)r&axoffsetr)r)r*r"Us     zCircuitPlot._create_figurec Cs|jd}|jd}||j||jf}t|jD]I}|j||j|f}t||d|jd}|j||j rbd}|j |j |rDd}|jj |d|j ||dt|j ||j |jddddq|dS) z&Plot the wires of the circuit diagram.rr;kcolorlwg?center)sizerIhavaN)r2r.rangerr1Line2D linewidthrDadd_linerrgettext label_buffer render_labelfontsize_plot_measured_wires)r&xstartxstopxdataiydatalineinit_label_bufferr)r)r*r#gs,    zCircuitPlot._plot_wiresc Cs|}|jd}d}|D]+}|j||||jf}|j|||j||f}t||d|jd}|j|q t| D]K\}} t | t t fr| j | j} | D]7} | |vr|j||j|| krt| t| f}|j|||j||f}t||d|jd}|j|qRq?dS)Nr;g{Gz?rGrH) _measurementsr2r.r1rPrQrDrR enumerate_gates isinstancerrcontrolstargetsminmax) r& ismeasuredrZdyimr[r]r^r\gwireswirer)r)r*rX~s8   z CircuitPlot._plot_measured_wirescCsVg}t|jtrt|jjD] }t|tr||q|St|jtr)||j|S)z/Create a list of all gates in the circuit plot.)rcrrreversedrrappend)r&gatesrkr)r)r*rbs    zCircuitPlot._gatescCs&t|D] \}}|||qdS)z0Iterate through the gates and plot each of them.N)rarb plot_gate)r&r\gater)r)r*r$szCircuitPlot._plot_gatescCs\i}t|D]#\}}t|ddr+|jD]}||vr&|||kr%|||<q|||<qq|S)zReturn a dict ``{i:j}`` where i is the index of the wire that has been measured, and j is the gate where the wire is measured. measurementF)rarbgetattrre)r&rhr\rktargetr)r)r*r`s    zCircuitPlot._measurementscCs|jD]}|dqdS)NF)r>findobj set_clip_on)r&or)r)r*r%s zCircuitPlot._finishc CsB|j|}|j|}|jj|||dddddd|jd|jddS)z#Draw a box for a single qubit gate.rGrKr5TecfcfillrJ)rIrMrNbboxrLN)r2r1rDrTrQrW)r&tgate_idxwire_idxxyr)r)r* one_qubit_boxs   zCircuitPlot.one_qubit_boxcCst|jt|jdS)z>> from sympy.physics.quantum.circuitplot import render_label >>> render_label('q0') '$\\left|q0\\right\\rangle$' >>> render_label('q0', {'q0':'0'}) '$\\left|q0\\right\\rangle=\\left|0\\right\\rangle$' z-$\left|%s\right\rangle=\left|%s\right\rangle$z$\left|%s\right\rangle$)rS)labelrinitr)r)r*rV.s  rVqcsfddtDS)aAutogenerate labels for wires of quantum circuits.
