How do I plot a custom 2-qubit gate in SymPy?
The following doesn't seem to work for me:
from sympy import *
from sympy.physics.quantum.gate import UGate
from sympy.physics.quantum.circuitplot import circuit_plot
g = UGate((0,1), eye(4), 2) # define custom 2-qubit gate
circuit_plot(g, 2) # plot circuit
Output:
I expected the gate to be drawn across the 2 qubit wires.
