cirq_pasqal.pasqal_device.PasqalDevice

A generic Pasqal device.

cirq_pasqal.pasqal_device.PasqalDevice(
    qubits: Sequence[cirq.Qid]
) -> None

The most general of Pasqal devices, enforcing only restrictions expected to be shared by all future devices. Serves as the parent class of all Pasqal devices, but can also be used on its own for hosting a nearly unconstrained device. When used as a circuit's device, the qubits have to be of the type cirq.NamedQubit and assumed to be all connected, the idea behind it being that after submission, all optimization and transpilation necessary for its execution on the specified device are handled internally by Pasqal.

qubits (NamedQubit): Qubits on the device, exclusively unrelated to a physical position.

TypeError If the wrong qubit type is provided.
ValueError If the number of qubits is greater than the devices maximum.

maximum_qubit_number

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

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

An operation can be added if the moment with the operation added is valid.

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

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

Raises
ValueError If either of the given moment or operation is invalid

decompose_operation

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

THIS FUNCTION IS DEPRECATED.

IT WILL BE REMOVED IN cirq v0.15.

Use PasqalConverter() to decompose operation instead.

is_pasqal_device_op(
    op: cirq.Operation
) -> bool

qid_pairs

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.

validate_circuit

View source

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

Raises an error if the given circuit is invalid on this device.

A circuit is invalid if any of its moments are invalid or if there is a non-empty moment after a moment with a measurement.

Args
circuit The circuit to validate

Raises
ValueError If the given circuit can't be run on this device

validate_moment

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
)

Raises an error if the given operation is invalid on this device.

Args
operation The operation to validate.

Raises
ValueError If the operation is not valid.
NotImplementedError If the operation is a measurement with an invert mask.
