# Fake7QPulseV1

*class* `qiskit.providers.fake_provider.Fake7QPulseV1`

[GitHub](https://github.com/Qiskit/qiskit/tree/stable/1.1/qiskit/providers/fake_provider/backends_v1/fake_7q_pulse/fake_7q_pulse_v1.py#L21-L44)

Bases: [`FakePulseBackend`](/docs/api/qiskit/1.1/providers_fake_provider#qiskit.providers.fake_provider.FakePulseBackend "qiskit.providers.fake_provider.fake_pulse_backend.FakePulseBackend")

A fake **pulse** backend with the following characteristics:

- num\_qubits: 7

- coupling\_map:

  > ```text
  > 0 ↔ 1 ↔ 3 ↔ 5 ↔ 6
  >     ↕       ↕
  >     2       4
  > ```

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

- **scheduled instructions:**

  \# `{'u3', 'id', 'measure', 'u2', 'x', 'u1', 'sx', 'rz'}` for all individual qubits # `{'cx'}` for all edges # `{'measure'}` for (0, 1, 2, 3, 4, 5, 6)

FakeBackend initializer.

**Parameters**

- **configuration** ([*BackendConfiguration*](/docs/api/qiskit/1.1/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

## Attributes

### backend\_name

Default value: `'fake_7q_pulse_v1'`

### conf\_filename

Default value: `'conf_nairobi.json'`

### defs\_filename

Default value: `'defs_nairobi.json'`

### dirname

Default value: `'/home/runner/work/qiskit/qiskit/.tox/docs/lib/python3.9/site-packages/qiskit/providers/fake_provider/backends_v1/fake_7q_pulse'`

### 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()`](#qiskit.providers.fake_provider.Fake7QPulseV1.run "qiskit.providers.fake_provider.Fake7QPulseV1.run") method.

### props\_filename

Default value: `'props_nairobi.json'`

### version

Default value: `1`
