<Admonition title="Deprecated since version 1.2" type="danger">
|
||
The class `qiskit.providers.fake_provider.fake_backend.FakeBackend` is deprecated as of qiskit 1.2. It will be removed in the 2.0 release. Fake backends using BackendV1 are deprecated in favor of [`GenericBackendV2`](qiskit.providers.fake_provider.GenericBackendV2 "qiskit.providers.fake_provider.GenericBackendV2"). You can convert BackendV1 to [`BackendV2`](qiskit.providers.BackendV2 "qiskit.providers.BackendV2") with [`BackendV2Converter`](qiskit.providers.BackendV2Converter "qiskit.providers.BackendV2Converter").

|
||
* **time\_alive** ([*int*](https://docs.python.org/3/library/functions.html#int "(in Python v3.13)")) – time to wait before returning result
