The problem is described in the title. I am trying to obtain a unitary matrix for a specific quantum circuit using pennylane, but I can’t find the available qml. function to get it. Thanks for the help!
Hi @cyrie_wang! If you are using the latest GitHub version of PennyLane, installable using
pip install git+https://github.com/PennyLaneAI/pennylane.git#egg=pennylane
then you can access the new
def circuit(theta): qml.RX(theta, wires=1) qml.PauliZ(wires=0)
We can use
get_unitary_matrix() to generate a new function that returns the unitary matrix corresponding to the function circuit:
>>> get_matrix = get_unitary_matrix(circuit) >>> theta = np.pi/4 >>> get_matrix(theta)
wonderful! thank you so much.
