About

Qiskit 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.

Documentation

All documentation is available at https://qiskit.github.io/qiskit-addon-cutting/.

Installation

We encourage installing this package via pip, when possible.

pip install 'qiskit-addon-cutting'

For information on installing from source, running in a container, and platform support, refer to the installation instructions in the documentation.

Deprecation Policy

We follow semantic versioning and are guided by the principles in Qiskit's deprecation policy. 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.
