cirq.DecompositionContext

Stores common configurable options for decomposing composite gates into simpler operations.

cirq.DecompositionContext(
    qubit_manager: cirq.QubitManager, extract_global_phases: bool = False
)

Args
`qubit_manager`	A `cirq.QubitManager` instance to allocate clean / dirty ancilla qubits as part of the decompose protocol.
`extract_global_phases`	If set, will extract the global phases from `DECOMPOSE_TARGET_GATESET` into independent global phase operations.

Attributes
`qubit_manager`	Dataclass field
`extract_global_phases`	Dataclass field

Methods

extracting_global_phases() -> DecompositionContext

Returns a copy with the extract_global_phases field set.

__eq__(
    other
)

Return self==value.

Class Variables
extract_global_phases	`False`
