max_shots

maximum number of shots supported.

Initialize a QasmBackendConfiguration Object

Parameters

  • backend_version (str) – The backend version in the form X.Y.Z

  • n_qubits (int) – the number of qubits for the backend

  • basis_gates (list) – The list of strings for the basis gates of the backends

  • gates (list) – The list of GateConfig objects for the basis gates of the backend

  • local (bool) – True if the backend is local or False if remote

  • simulator (bool) – True if the backend is a simulator

  • conditional (bool) – True if the backend supports conditional operations
