cirq.testing.ValidatingTestDevice

A fake device that was created to ensure certain Device validation features are leveraged in Circuit functions.

Inherits From: Device

cirq.testing.ValidatingTestDevice(
    qubits: AbstractSet[cirq.Qid],
    name: str = 'ValidatingTestDevice',
    allowed_gates: Tuple[type, ...] = (ops.Gate,),
    allowed_qubit_types: Tuple[type, ...] = (devices.GridQubit,),
    validate_locality: bool = False,
    auto_decompose_gates: Tuple[type, ...] = tuple()
)

It contains the minimum set of features that tests require. Feel free to extend the features here as needed.

qubits set of qubits on this device
name the name for repr
allowed_gates tuple of allowed gate types
allowed_qubit_types tuple of allowed qubit types
validate_locality if True, device will validate 2 qubit operations (except MeasurementGateOperations) whether the two qubits are adjacent. If True, GridQubits are assumed to be part of the allowed_qubit_types
auto_decompose_gates when set, for given gates it calls the cirq.decompose protocol

metadata Returns the associated Metadata with the device if applicable.
