# Fake5QV1

*class* `qiskit.providers.fake_provider.Fake5QV1`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.3/qiskit/providers/fake_provider/backends_v1/fake_5q/fake_5q_v1.py#L21-L41)

Bases: [`FakeQasmBackend`](/docs/api/qiskit/1.3/providers_fake_provider#qiskit.providers.fake_provider.FakeQasmBackend "qiskit.providers.fake_provider.fake_qasm_backend.FakeQasmBackend")

A fake backend with the following characteristics:

- num\_qubits: 5

- coupling\_map:

  > ```text
  >     1
  >   / |
  > 0 - 2 - 3
  >     | /
  >     4
  > ```

- basis\_gates: `["id", "rz", "sx", "x", "cx", "reset"]`

> **Deprecated since version 1.2**
>
> 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`](/docs/api/qiskit/1.3/qiskit.providers.fake_provider.GenericBackendV2 "qiskit.providers.fake_provider.GenericBackendV2"). You can convert BackendV1 to [`BackendV2`](/docs/api/qiskit/1.3/qiskit.providers.BackendV2 "qiskit.providers.BackendV2") with [`BackendV2Converter`](/docs/api/qiskit/1.3/qiskit.providers.BackendV2Converter "qiskit.providers.BackendV2Converter").

**Parameters**

- **configuration** ([*BackendConfiguration*](/docs/api/qiskit/1.3/qiskit.providers.models.BackendConfiguration "qiskit.providers.models.BackendConfiguration")) – backend configuration
- **time\_alive** ([*int*](https://docs.python.org/3/library/functions.html#int)) – time to wait before returning result
