I generated a quantum circuit in qiskit, and use plot_state_city
to plot the density matrix. I am wondering if there is any way I can add numerical values on every element.
Example:
from qiskit import QuantumCircuit, execute
from qiskit.quantum_info import DensityMatrix
from qiskit.visualization import plot_state_city
%matplotlib inline
qc = QuantumCircuit(2)
qc.h(0)
qc.cx(0,1)
state = DensityMatrix.from_instruction(qc)
plot_state_city(state)
