cirq.two_qubit_matrix_to_cz_isometry

Decomposes a 2q operation into at-most 2 CZs + 1q rotations; assuming q0 is initially |0>.

cirq.two_qubit_matrix_to_cz_isometry(
    q0: 'cirq.Qid',
    q1: 'cirq.Qid',
    mat: np.ndarray,
    allow_partial_czs: bool = False,
    atol: float = 1e-08,
    clean_operations: bool = True
) -> List['cirq.Operation']

The method implements isometry from one to two qubits; assuming qubit q0 is always in the |0> state. See Appendix B.1 of https://arxiv.org/abs/1501.06911 for more details.

q0 The first qubit being operated on. This is assumed to always be in the |0> state.
q1 The other qubit being operated on.
mat Defines the unitary operation to apply to the pair of qubits.
allow_partial_czs Enables the use of Partial-CZ gates.
atol A limit on the amount of absolute error introduced by the construction.
clean_operations Enables optimizing resulting operation list by merging single qubit operations and ejecting phased Paulis and Z operations.

A list of operations implementing the action of the given unitary matrix, assuming the input qubit q0 is in the |0> state.
