metadata Returns the associated Metadata with the device if applicable.

Methods

can_add_operation_into_moment

View source

can_add_operation_into_moment(
    operation: 'cirq.Operation', moment: 'cirq.Moment'
) -> bool

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

can_add_operation_into_moment will be removed in the future. Consider using device.validate_circuit instead.

Determines if it's possible to add an operation into a moment.

    For example, on the XmonDevice two CZs shouldn't be placed in the same
    moment if they are on adjacent qubits.

    Args:
        operation: The operation being added.
        moment: The moment being transformed.

    Returns:
        Whether or not the moment will validate after adding the operation.

decompose_operation

View source

decompose_operation(
    operation: 'cirq.Operation'
) -> 'cirq.OP_TREE'

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

Devices will no longer decompose operations.

Returns a device-valid decomposition for the given operation.

    This method is used when adding operations into circuits with a device
    specified, to avoid spurious failures due to e.g. using a Hadamard gate
    that must be decomposed into native gates.

qid_pairs

View source

qid_pairs() -> Optional[FrozenSet['cirq.SymmetricalQidPair']]

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

qubit coupling data can now be found in device.metadata if provided.

Returns a set of qubit edges on the device, if possible.

    This property can be overridden in child classes for special handling.
    The default handling is: GridQids and LineQids will have neighbors as
    edges, and others will be fully connected.

    Returns:
        If the device has a finite set of qubits, then a set of all edges
        on the device is returned.

        If the device has no well defined finite set of qubits (e.g.
        `cirq.UnconstrainedDevice` has this property), then `None` is
        returned.

qubit_set

View source

qubit_set() -> Optional[AbstractSet['cirq.Qid']]

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

Use metadata.qubit_set if applicable.

Returns a set or frozenset of qubits on the device, if possible.

    Returns:
        If the device has a finite set of qubits, then a set or frozen set
        of all qubits on the device is returned.

        If the device has no well defined finite set of qubits (e.g.
        `cirq.UnconstrainedDevice` has this property), then `None` is
        returned.

validate_circuit

View source

validate_circuit(
    circuit: 'cirq.AbstractCircuit'
) -> None

Raises an exception if a circuit is not valid.

Args
circuit The circuit to validate.

Raises
ValueError The circuit isn't valid for this device.

validate_moment

View source

validate_moment(
    moment: 'cirq.Moment'
) -> None

Raises an exception if a moment is not valid.

Args
moment The moment to validate.

Raises
ValueError The moment isn't valid for this device.

validate_operation

View source

validate_operation(
    operation: 'cirq.Operation'
) -> None

Raises an exception if an operation is not valid.

Args
operation The operation to validate.

Raises
ValueError The operation isn't valid for this device.
