cirq_ionq.ionq_devices.IonQAPIDevice

A device that uses the QIS gates exposed by the IonQ API.

cirq_ionq.ionq_devices.IonQAPIDevice(
    qubits: Union[Sequence[cirq.LineQubit], int], atol=1e-08
)

When using this device in constructing a circuit, it will convert one and two qubit gates that are not supported by the API into those supported by the API if they have a unitary matrix (support the unitary protocol).

Note that this device does not do any compression of the resulting circuit, i.e. it may result in a series of single qubit gates that could be executed using far fewer elements.

The gates supported by the API are

qubits The qubits upon which this device acts or the number of qubits. If the number of qubits, then the qubits will be cirq.LineQubits from 0 to this number minus one.
atol The absolute tolerance used for gate calculations and decompositions.

metadata Returns the associated Metadata with the device if applicable.
