# cirq.single_qubit_matrix_to_phased_x_z¶

cirq.single_qubit_matrix_to_phased_x_z(mat: numpy.ndarray, atol: float = 0) → List[cirq.ops.gate_features.SingleQubitGate][source]

Implements a single-qubit operation with a PhasedX and Z gate.

If one of the gates isn’t needed, it will be omitted.

Parameters: mat – The 2x2 unitary matrix of the operation to implement. atol – A limit on the amount of error introduced by the construction. A list of gates that, when applied in order, perform the desired operation.
