cirq.single_qubit_matrix_to_pauli_rotations

cirq.single_qubit_matrix_to_pauli_rotations(mat: numpy.ndarray, tolerance: float = 0) → List[Tuple[cirq.ops.pauli.Pauli, float]][source]

Implements a single-qubit operation with few rotations.

Parameters:
  • mat – The 2x2 unitary matrix of the operation to implement.
  • tolerance – A limit on the amount of error introduced by the construction.
Returns:

A list of (Pauli, half_turns) tuples that, when applied in order, perform the desired operation.
