cirq.SimulationProductState

A container for a Qid-to-SimulationState dictionary.

Inherits From: SimulationStateBase

cirq.SimulationProductState( sim_states: dict[cirq.Qid | None, TSimulationState], qubits: Sequence[cirq.Qid], split_untangled_states: bool, classical_data: (cirq.ClassicalDataStore | None) = None )

sim_states The SimulationState dictionary. This will not be copied; the original reference will be kept here.
qubits The canonical ordering of qubits.
split_untangled_states If True, optimizes operations by running unentangled qubit sets independently and merging those states at the end.
classical_data The shared classical data container for this simulation.

log_of_measurement_results Gets the log of measurement results.

Methods

apply_operation

View source

apply_operation( op: cirq.Operation )

copy

View source

copy( deep_copy_buffers: bool = True ) -> cirq.SimulationProductState[TSimulationState]

Creates a copy of the object.

Args
deep_copy_buffers If True, buffers will also be deep-copied. Otherwise the copy will share a reference to the original object's buffers.

Returns
A copied instance.

create_merged_state

View source

create_merged_state() -> TSimulationState

Creates a final merged state.

get

get( key, default=None )

D.get(k[,d]) -> D[k] if k in D, else d. d defaults to None.

items

items()

D.items() -> a set-like object providing a view on D's items

keys

keys()

D.keys() -> a set-like object providing a view on D's keys

sample

View source

sample( qubits: list[cirq.Qid], repetitions: int = 1, seed: cirq.RANDOM_STATE_OR_SEED_LIKE = None ) -> np.ndarray

Samples the state value.

values

values()

D.values() -> an object providing a view on D's values

__contains__

__contains__( key )

__eq__

__eq__( other )

Return self==value.

__getitem__

View source

__getitem__( item: (cirq.Qid | None) ) -> TSimulationState

Gets the item associated with the qubit.

__iter__

View source

__iter__() -> Iterator[cirq.Qid | None]

Iterates the keys of the mapping.

__len__

View source

__len__() -> int

Gets the number of items in the mapping.
