# Qiskit addons

Qiskit addons are a collection of research capabilities for enabling algorithm discovery at the utility scale. These capabilities build on Qiskit's performant foundation of tools for creating and running quantum algorithms. They are provided as modular software components that can plug into a [workflow](/docs/guides/intro-to-patterns) to scale or design new quantum algorithms.

### Propagated noise absorption

Propagated noise absorption (PNA) uses Pauli propagation to absorb information from a noise model into a target observable. Measuring this modified observable has the effect of mitigating the noise as represented by the model.

### Shaded lightcones

The shaded lightcones addon uses Pauli propagation to reduce the number of error terms accounted for in a noise model according to the specifics of the target observable. This has the effect of reducing the sampling overhead for probabilistic error cancellation (PEC) workflows.
