cirq.unroll_circuit_op

Unrolls (tagged) cirq.CircuitOperations while preserving the moment structure.

cirq.unroll_circuit_op(
    circuit: CIRCUIT_TYPE,
    *,
    deep: bool = False,
    tags_to_check: Optional[Sequence[Hashable]] = (MAPPED_CIRCUIT_OP_TAG,)
) -> CIRCUIT_TYPE

Each moment containing a matching circuit operation is expanded into a list of moments with the unrolled operations, hence preserving the original moment structure.

Args
`circuit`	Input circuit to apply the transformations on. The input circuit is not mutated.
`deep`	If true, the transformer primitive will be recursively applied to all circuits wrapped inside circuit operations.
`tags_to_check`	If specified, only circuit operations tagged with one of the `tags_to_check` are unrolled.

Returns
Copy of input circuit with (Tagged) CircuitOperation's expanded in a moment preserving way.
