Plotting extension for quantum circuit visualizations

YaoPlots

Example 1: Visualize a QBIR define in Yao

using YaoExtensions, YaoPlots
using Compose

# show a qft circuit
plot(qft_circuit(5))

If you are using a Pluto/Jupyter notebook, Atom/VSCode editor, you should see the following image in your plotting panel.

Otherwise, you might be interested to learn how to save it as an image.

See more examples.

Adjusting the plot attributes

Various attributes of the visualizations can be altered. The plot can be modifiend, if we change the following attributes

• YaoPlots.CircuitStyles.linecolor[] for line color, default value being "#000000" (black color)
• YaoPlots.CircuitStyles.gate_bgcolor[] for background color of square blocks, the default value being "#FFFFFF" (white color)
• YaoPlots.CircuitStyles.textcolor[] for text color, default value being "#000000
• YaoPlots.CircuitStyles.lw[] for line width, default value being 1pt
• YaoPlots.CircuitStyles.textsize[] for text size, default value being 16pt
• YaoPlots.CircuitStyles.paramtextsize[] for parameter text size, for parameterized gates, default value being 10pt

For example,

using YaoPlots, Yao
YaoPlots.CircuitStyles.linecolor[] = "pink" 
YaoPlots.CircuitStyles.gate_bgcolor[] = "yellow" 
YaoPlots.CircuitStyles.textcolor[] = "#000080" # the navy blue color
YaoPlots.CircuitStyles.fontfamily[] = "JuliaMono"
YaoPlots.CircuitStyles.lw[] = 2.5pt
YaoPlots.CircuitStyles.textsize[] = 13pt
YaoPlots.CircuitStyles.paramtextsize[] = 8pt
		
plot(chain(3, put(1=>X), repeat(3, H), put(2=>Y), repeat(3, Rx(π/2))))

Example 2: Visualize ZX-diagrams in ZXCalculus

using ZXCalculus, YaoPlots
using Compose

function generate_example()
    zxd = ZXDiagram(4)
    push_gate!(zxd, Val{:Z}(), 1, 3//2)
    push_gate!(zxd, Val{:H}(), 1)
    push_gate!(zxd, Val{:Z}(), 1, 1//2)
    push_gate!(zxd, Val{:H}(), 4)
    push_gate!(zxd, Val{:CZ}(), 4, 1)
    push_gate!(zxd, Val{:CNOT}(), 1, 4)
    push_gate!(zxd, Val{:H}(), 1)
    push_gate!(zxd, Val{:H}(), 4)
    push_gate!(zxd, Val{:Z}(), 1, 1//4)
    push_gate!(zxd, Val{:Z}(), 4, 3//2)
    push_gate!(zxd, Val{:X}(), 4, 1//1)
    push_gate!(zxd, Val{:H}(), 1)
    push_gate!(zxd, Val{:Z}(), 4, 1//2)
    push_gate!(zxd, Val{:X}(), 4, 1//1)
    push_gate!(zxd, Val{:Z}(), 2, 1//2)
    push_gate!(zxd, Val{:CNOT}(), 3, 2)
    push_gate!(zxd, Val{:H}(), 2)
    push_gate!(zxd, Val{:CNOT}(), 3, 2)
    push_gate!(zxd, Val{:Z}(), 2, 1//4)
    push_gate!(zxd, Val{:Z}(), 3, 1//2)
    push_gate!(zxd, Val{:H}(), 2)
    push_gate!(zxd, Val{:H}(), 3)
    push_gate!(zxd, Val{:Z}(), 3, 1//2)
    push_gate!(zxd, Val{:CNOT}(), 3, 2)

    return zxd
end

zxd = generate_example() # define a example
plot(zxd) # draw a ZX-diagram
plot(ZXGraph(zxd)) # draw a graph-like ZX-diagram

If you are using a Pluto/Jupyter notebook, Atom/VSCode editor, you should see the following images in your plotting panel.
