cirq.IonDevice

A device with qubits placed on a line.

Inherits From: Device

cirq.IonDevice(
    measurement_duration: 'cirq.DURATION_LIKE',
    twoq_gates_duration: 'cirq.DURATION_LIKE',
    oneq_gates_duration: 'cirq.DURATION_LIKE',
    qubits: Iterable[cirq.LineQubit]
) -> None

Qubits have all-to-all connectivity.

measurement_duration The maximum duration of a measurement.
twoq_gates_duration The maximum duration of a two qubit operation.
oneq_gates_duration The maximum duration of a single qubit operation.
qubits Qubits on the device, identified by their x location.

TypeError If not all the qubits supplied are cirq.LineQubits.

metadata Returns the associated Metadata with the device if applicable.

Methods

at

View source

at(
    position: int
) -> Optional[cirq.LineQubit]

Returns the qubit at the given position, if there is one, else None.

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_circuit

View source

decompose_circuit(
    circuit: cirq.Circuit
) -> cirq.Circuit

decompose_operation

View source

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

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

Use cirq.ConvertToIonGates() instead to decompose operations.

duration_of

View source

duration_of(
    operation
)

neighbors_of

View source

neighbors_of(
    qubit: cirq.LineQubit
) -> Iterable[cirq.LineQubit]

Returns the qubits that the given qubit can interact with.

qid_pairs

View source

qid_pairs() -> 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.

Qubits have all-to-all connectivity, so returns all pairs.

    Returns:
        All qubit pairs on the device.

qubit_set

View source

qubit_set() -> FrozenSet['cirq.LineQubit']

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

Use metadata.qubit_set if applicable.

validate_circuit

View source

validate_circuit(
    circuit: cirq.AbstractCircuit
)

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_gate

View source

validate_gate(
    gate: cirq.Gate
)

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
)

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.
