I am able to visualize vectors on a bloch sphere using Qiskit as follows:
from qiskit.quantum_info import Statevector from qiskit.visualization import plot_bloch_vector %matplotlib inline sv =  sv.append([0,1,0]) sv.append([0,0,1]) sv.append([1,0,0]) fig = plot_bloch_vector(sv) fig
The code above yields the following result (which looks good):
Now I would like to adjust the colors of each vector. The API of Qiskit seems not to provide any color parameter for
plot_bloch_vector. Maybe we can manipulate the
fig object directly or find another way to adjust vector colors?
