FakeManilaV2

qiskit.providers.fake_provider.FakeManilaV2

Bases: FakeBackendV2

A fake 5 qubit backend.

FakeBackendV2 initializer.


Attributes

backend_name

= 'fake_manila'

conf_filename

= 'conf_manila.json'

coupling_map

Return the CouplingMap object

defs_filename

= 'defs_manila.json'

dirname

= '/home/runner/work/qiskit/qiskit/.tox/docs/lib/python3.9/site-packages/qiskit/providers/fake_provider/backends/manila'

dt

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.

dtm

Return the system time resolution of output signals

Returns

The output signal timestep in seconds.

instruction_durations

Return the InstructionDurations object.

instruction_schedule_map

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

instructions

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

max_circuits

meas_map

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

num_qubits

Return the number of qubits the backend has.

operation_names

A list of instruction names that the backend supports.

operations

A list of Instruction instances that the backend supports.

options

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.

props_filename

= 'props_manila.json'

provider

Return the backend Provider.

Returns

the Provider responsible for the backend.

Return type

Provider

target

A qiskit.transpiler.Target object for the backend.

Return type

Target

version

= 2

name

Name of the backend.

description

Optional human-readable description.

online_date

Date that the backend came online.

backend_version

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


Methods

acquire_channel

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

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 (opens in a new tab)[int (opens in a new tab)]) – Tuple or list of qubits of the form (control_qubit, target_qubit).

Returns

The multi qubit control line.

Return type

List[ControlChannel]

drive_channel

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

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_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 (opens in a new tab) |List (opens in a new tab)[int (opens in a new tab)]) – 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 (opens in a new tab) – if the backend doesn’t support querying the qubit properties

Return type

QubitProperties | List (opens in a new tab)[QubitProperties]

run

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

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

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 (opens in a new tab) – If the field passed in is not part of the options
