euler_angles_1q(unitary_matrix)

DEPRECATED: Compute Euler angles for a single-qubit gate.

Find angles (theta, phi, lambda) such that unitary_matrix = phase * Rz(phi) * Ry(theta) * Rz(lambda)

Parameters

unitary_matrix (ndarray) – 2x2 unitary matrix

Returns

(theta, phi, lambda) Euler angles of SU(2)

Return type

tuple

Raises

QiskitError – if unitary_matrix not 2x2, or failure
