## Get started with the backend primitives
Unlike provider-specific primitives, backend primitives are generic implementations that can be used with an arbitrary
Unlike provider-specific primitives, backend primitives are generic implementations that can be used with an arbitrary
`backend` object, as long as it implements the [`Backend`](/api/qiskit/qiskit.providers.Backend) interface.
The `Sampler` primitive can be run with any provider by using [`qiskit.primitives.BackendSamplerV2`](/api/qiskit/qiskit.primitives.BackendSamplerV2)
or the legacy V1 implementation, [`qiskit.primitives.BackendSampler`](/api/qiskit/qiskit.primitives.BackendSampler).
Likewise, the `Estimator` primitive can be run with any provider using [`qiskit.primitives.BackendEstimatorV2`](../api/qiskit/qiskit.primitives.BackendEstimatorV2),
or the legacy V1 implementation, [`qiskit.primitives.BackendEstimator`](/api/qiskit/qiskit.primitives.BackendEstimator).

### Similarities and differences between backend and Runtime primitives (V2)
- The inputs to [`qiskit.primitives.BackendSamplerV2`](/api/qiskit/qiskit.primitives.BackendSamplerV2) and [`qiskit.primitives.BackendEstimatorV2`](../api/qiskit/qiskit.primitives.BackendEstimatorV2)
follow the same PUB format as the primitives in Qiskit Runtime, so do the outputs, see (link to https://docs.quantum.ibm.com/guides/primitive-input-output).

However, there can be differences in the fields of the returned metadata.
- The [`qiskit.primitives.BackendEstimatorV2`](/api/qiskit/qiskit.primitives.BackendEstimatorV2) class offers no measurement or gate error mitigation implementations out-of-the-box, as
backend primitives are designed to run locally in the user's machine.

- The [`qiskit.primitives.BackendSamplerV2`](/api/qiskit/qiskit.primitives.BackendSamplerV2) class requires a backend that supports the `memory` option.
- The backend primitives V2 interfaces expose custom `Sampler` and `Estimator` `Options` for that are different to the Runtime implementations.
