Bases: FakeBackend

Configurable backend.

Creates backend based on provided configuration.

Parameters:

  • name (str) -- Name of the backend.

  • n_qubits (int) -- Number of qubits in the backend.

  • version (str | None) -- Version of the fake backend.

  • coupling_map (List[List[int]] | None) -- Coupling map.

  • basis_gates (List[str] | None) -- Basis gates of the backend.

  • qubit_t1 (float | List[float] | None) -- Longitudinal coherence times.

  • qubit_t2 (float | List[float] | None) -- Transverse coherence times.

  • qubit_frequency (float | List[float] | None) -- Frequency of qubits.

  • qubit_readout_error (float | List[float] | None) -- Readout error of qubits.

  • single_qubit_gates (List[str] | None) -- List of single qubit gates for backend properties.

  • dt (float | None) -- Discretization of the input time sequences.

  • std (float | None) -- Standard deviation of the generated distributions.

  • seed (int | None) -- Random seed.

Attributes

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.

version = 1#

Methods

configuration()#

Return the backend configuration.

Returns:

the configuration for the backend.

Return type:

BackendConfiguration

defaults()[source]#

Return backend defaults.

name()#

Return the backend name.

Returns:

the name of the backend.

Return type:

str

properties()[source]#

Return backend properties

provider()#

Return the backend Provider.

Returns:

run(run_input, **kwargs)#

Main job in simulator

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

status()#

Return the backend status.

Returns:

the status of the backend.

Return type:

BackendStatus
