Bases: FakeBackend
Configurable backend.
Creates backend based on provided configuration.
Parameters
- name (str (opens in a new tab)) – Name of the backend.
- n_qubits (int (opens in a new tab)) – Number of qubits in the backend.
- version (str (opens in a new tab) | None) – Version of the fake backend.
- coupling_map (List (opens in a new tab)[List (opens in a new tab)[int (opens in a new tab)]] | None) – Coupling map.
- basis_gates (List (opens in a new tab)[str (opens in a new tab)] | None) – Basis gates of the backend.
- qubit_t1 (float (opens in a new tab) |List (opens in a new tab)[float (opens in a new tab)] | None) – Longitudinal coherence times.
- qubit_t2 (float (opens in a new tab) |List (opens in a new tab)[float (opens in a new tab)] | None) – Transverse coherence times.
- qubit_frequency (float (opens in a new tab) |List (opens in a new tab)[float (opens in a new tab)] | None) – Frequency of qubits.
- qubit_readout_error (float (opens in a new tab) |List (opens in a new tab)[float (opens in a new tab)] | None) – Readout error of qubits.
- single_qubit_gates (List (opens in a new tab)[str (opens in a new tab)] | None) – List of single qubit gates for backend properties.
- dt (float (opens in a new tab) | None) – Discretization of the input time sequences.
- std (float (opens in a new tab) | None) – Standard deviation of the generated distributions.
- seed (int (opens in a new tab) | 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.
