# ResilienceOptions

*class* `ResilienceOptions(*args, **kwargs)`

[GitHub](https://github.com/Qiskit/qiskit-ibm-runtime/tree/stable/0.26/qiskit_ibm_runtime/options/resilience_options.py#L102-L139)

Resilience options for V1 primitives.

**Parameters**

- **noise\_factors** – An list of real valued noise factors that determine by what amount the circuits’ noise is amplified. Only applicable for `resilience_level=2`. Default: `None`, and (1, 3, 5) if resilience level is 2.
- **noise\_amplifier** – A noise amplification strategy. Currently only
- **resilience\_level=2.** (*"LocalFoldingAmplifier" is supported Only applicable for*) – Default: “LocalFoldingAmplifier”.
- **extrapolator** – An extrapolation strategy. One of `"LinearExtrapolator"`, `"QuadraticExtrapolator"`, `"CubicExtrapolator"`, `"QuarticExtrapolator"`. Note that `"CubicExtrapolator"` and `"QuarticExtrapolator"` require more noise factors than the default. Only applicable for `resilience_level=2`. Default: `None`, and `LinearExtrapolator` if resilience level is 2.
