### About
[Qiskit addons](https://docs.quantum.ibm.com/guides/addons) are a collection of modular tools for building utility-scale workloads powered by Qiskit.
This package implements circuit cutting. In this technique, a handful of gates and/or wires are cut, resulting in smaller circuits that are better suited for execution on hardware. The result of the original circuit can then be reconstructed; however, the trade-off is that the overall number of shots must be increased by a factor exponential in the number of cuts.
For a more detailed discussion on circuit cutting, check out our [technical guide](https://qiskit.github.io/qiskit-addon-cutting/explanation/index.html#overview-of-circuit-cutting).
----------------------------------------------------------------------------------------------------
### Documentation
All documentation is available at https://qiskit.github.io/qiskit-addon-cutting/.
----------------------------------------------------------------------------------------------------
### Installation
We encourage installing this package via ``pip``, when possible.
```bash
pip install 'qiskit-addon-cutting'
```
For information on installing from source, running in a container, and platform support, refer to the [installation instructions](https://qiskit.github.io/qiskit-addon-cutting/install.html) in the documentation.
----------------------------------------------------------------------------------------------------
### Deprecation Policy
We follow [semantic versioning](https://semver.org/) and are guided by the principles in [Qiskit's deprecation policy](https://github.com/Qiskit/qiskit/blob/main/DEPRECATION.md). We may occasionally make breaking changes in order to improve the user experience. When possible, we will keep old interfaces and mark them as deprecated, as long as they can co-exist with the new ones. Each substantial improvement, breaking change, or deprecation will be documented in the [release notes](https://qiskit.github.io/qiskit-addon-cutting/release-notes.html).
