FakeSantiagoV2

Default value: 'fake_santiago'

Default value: 'conf_santiago.json'

Return the CouplingMap object

Default value: 'defs_santiago.json'

Default value: '/home/runner/work/qiskit/qiskit/qiskit/providers/fake_provider/backends/santiago'

Return the system time resolution of input signals

This is required to be implemented if the backend supports Pulse scheduling.

Returns

The input signal timestep in seconds. If the backend doesn’t define dt, None will be returned.

Return the system time resolution of output signals

Returns

The output signal timestep in seconds.

Return the InstructionDurations object.

Return the InstructionScheduleMap for the instructions defined in this backend’s target.

A list of Instruction tuples on the backend of the form (instruction, (qubits)

Return the grouping of measurements which are multiplexed This is required to be implemented if the backend supports Pulse scheduling.

Returns

The grouping of measurements which are multiplexed

Return the number of qubits the backend has.

A list of instruction names that the backend supports.

A list of Instruction instances that the backend supports.

Return the options for the backend

The options of a backend are the dynamic parameters defining how the backend is used. These are used to control the run() method.

Default value: 'props_santiago.json'

Return the backend Provider.

Returns

the Provider responsible for the backend.

Return type

Provider

A qiskit.transpiler.Target object for the backend.

Return type

Target

Default value: 2

Name of the backend.

Optional human-readable description.

Date that the backend came online.

Version of the backend being provided. This is not the same as BackendV2.version, which is the version of the Backend abstract interface.

acquire_channel(qubit)

Return the acquisition channel for the given qubit.

This is required to be implemented if the backend supports Pulse scheduling.

Returns

The Qubit measurement acquisition line.

Return type

AcquireChannel

control_channel(qubits)

Return the secondary drive channel for the given qubit

This is typically utilized for controlling multiqubit interactions. This channel is derived from other channels.

This is required to be implemented if the backend supports Pulse scheduling.

Parameters

qubits (Iterable[int]) – Tuple or list of qubits of the form (control_qubit, target_qubit).

Returns

The multi qubit control line.

Return type

List[ControlChannel]

drive_channel(qubit)

Return the drive channel for the given qubit.

This is required to be implemented if the backend supports Pulse scheduling.

Returns

The Qubit drive channel

Return type

DriveChannel

measure_channel(qubit)

Return the measure stimulus channel for the given qubit.

This is required to be implemented if the backend supports Pulse scheduling.

Returns

The Qubit measurement stimulus line

Return type

MeasureChannel

qubit_properties(qubit)

Return QubitProperties for a given qubit.

If there are no defined or the backend doesn’t support querying these details this method does not need to be implemented.

Parameters

qubit (int |List[int]) – The qubit to get the QubitProperties object for. This can be a single integer for 1 qubit or a list of qubits and a list of QubitProperties objects will be returned in the same order

Returns

The QubitProperties object for the specified qubit. If a list of qubits is provided a list will be returned. If properties are missing for a qubit this can be None.

Raises

NotImplementedError – if the backend doesn’t support querying the qubit properties

Return type

QubitProperties | List[QubitProperties]

run(run_input, **options)

Run on the fake backend using a simulator.

This method runs circuit jobs (an individual or a list of QuantumCircuit ) and pulse jobs (an individual or a list of Schedule or ScheduleBlock) using BasicAer or Aer simulator and returns a Job object.

If qiskit-aer is installed, jobs will be run using AerSimulator with noise model of the fake backend. Otherwise, jobs will be run using BasicAer simulator without noise.

Currently noisy simulation of a pulse job is not supported yet in FakeBackendV2.

Parameters

• run_input (QuantumCircuit orSchedule orScheduleBlock orlist) – An individual or a list of QuantumCircuit, ScheduleBlock, or Schedule objects to run on the backend.
• options – Any kwarg options to pass to the backend for running the config. If a key is also present in the options attribute/object then the expectation is that the value specified will be used instead of what’s set in the options object.

Returns

The job object for the run

Return type

Job

Raises

QiskitError – If a pulse job is supplied and qiskit-aer is not installed.

set_options(**fields)

Set the options fields for the backend

This method is used to update the options of a backend. If you need to change any of the options prior to running just pass in the kwarg with the new value for the options.

Parameters

fields – The fields to update the options

Raises

AttributeError – If the field passed in is not part of the options
