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 CreateCGateZnumpy matplotlibfromlistpyplot)Z import_kwargsZcatchc@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&E/tmp/pip-unpacked-wheel-_6tpq7m6/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'rIszCircuitPlot.updatecCsF|j}tjd|j||td}tjd|j||td}||_||_dS)zCreate the grid of wires.g)ZdtypeN)scalerZarangerfloatr _wire_grid _gate_grid)r#r*Z wire_gridZ gate_gridr&r&r'rMs 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)ZfigsizeZ facecolorZ edgecolorT)ZframeonrrequalN)rfigurerr*r_figureZ add_subplotZ set_axis_offZset_xlimr-Zset_ylimr,Z set_aspect_axes)r#Zaxoffsetr&r&r'rUs"    zCircuitPlot._create_figurec Cs|jd}|jd}||j||jf}t|jD]}|j||j|f}t||d|jd}|j||j r2d}|j |j |rd}|jj |d|j ||dt|j ||j |jddddq2|dS) z&Plot the wires of the circuit diagram.rr0kcolorlwg?center)sizer8havaN)r-r*rangerr,Line2D linewidthr4add_linerrgettext label_buffer render_labelfontsize_plot_measured_wires)r#ZxstartxstopxdataiydatalineZinit_label_bufferr&r&r'r gs4   zCircuitPlot._plot_wiresc Cs|}|jd}d}|D]V}|j||||jf}|j|||j||f}t||d|jd}|j|qt| D]\}} t | t t fr~| j | j} | D]n} | |kr|j||j|| krt| t| f}|j|||j||f}t||d|jd}|j|qq~dS)Nr0g{Gz?r6r7) _measurementsr-r*r,r?r@r4rA enumerate_gates isinstancerrcontrolstargetsminmax) r# ismeasuredrHZdyZimrIrKrLrJgZwiresZwirer&r&r'rG~s:  z CircuitPlot._plot_measured_wirescCsTg}t|jtr8t|jjD]}t|tr||qnt|jtrP||j|S)z/Create a list of all gates in the circuit plot.)rPrrreversedrrappend)r#ZgatesrVr&r&r'rOs    zCircuitPlot._gatescCs&t|D]\}}|||q dS)z0Iterate through the gates and plot each of them.N)rNrOZ plot_gate)r#rJZgater&r&r'r!szCircuitPlot._plot_gatescCs\i}t|D]F\}}t|ddr|jD]*}||krL|||krT|||<q*|||<q*q|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)rNrOgetattrrR)r#rUrJrVtargetr&r&r'rMs     zCircuitPlot._measurementscCs|jD]}|dq dS)NF)r3ZfindobjZ set_clip_on)r#or&r&r'r"szCircuitPlot._finishc CsB|j|}|j|}|jj|||dddddd|jd|jddS)z#Draw a box for a single qubit gate.r6r:r.TZecZfcfillr9)r8r<r=Zbboxr;N)r-r,r4rCr@rF)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$\left|%s\right\rangle$)rB)labelrinitr&r&r'rE.s  rEqcsfddtDS)aAutogenerate labels for wires of quantum circuits.
