# Ibm

For **`emulate`** on IBM Quantum, see [IBM hardware noise simulation (emulate)](../../user-guide/execution/cloud-providers/ibm-backends.md#ibm-hardware-noise-simulation-emulate) in the execution user guide.

### IBMBackendPreferences

Represents the backend preferences specific to IBM Quantum services.

Inherits from `BackendPreferences` and adds additional fields and validations
specific to IBM Quantum backends.

**Attributes:**

| Name                       | Type                           | Description                                                                                                           |
| -------------------------- | ------------------------------ | --------------------------------------------------------------------------------------------------------------------- |
| `backend_service_provider` | `ProviderTypeVendor.IBM_CLOUD` | Indicates the backend service provider as IBM Cloud.                                                                  |
| `access_token`             | `Optional[str]`                | The IBM Cloud access token to be used with IBM Quantum hosted backends. Defaults to `None`.                           |
| `channel`                  | `str`                          | Channel to use for IBM cloud backends. Defaults to `"ibm_cloud"`.                                                     |
| `instance_crn`             | `str`                          | The IBM Cloud instance CRN (Cloud Resource Name) for the IBM Quantum service.                                         |
| `run_via_classiq`          | `bool`                         | Run via Classiq's credentials. Defaults to `False`.                                                                   |
| `emulate`                  | `bool`                         | If True, run on a Classiq-hosted simulator with a noise model derived from the IBM backend name. Defaults to `False`. |
