About

Qiskit addons are a collection of modular tools for building utility-scale workloads powered by Qiskit.

This package contains the Qiskit addon for multi-product formulas (MPFs). These can be used to reduce the Trotter error of Hamiltonian dynamics.

This package currently contains the following submodules:

• qiskit_addon_mpf.static for working with static MPFs 1-2

Documentation

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

Installation

We encourage installing this package via pip, when possible:

pip install 'qiskit-addon-mpf'

For more installation information refer to these installation instructions.

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.

Contributing

The source code is available on GitHub.

The developer guide is located at CONTRIBUTING.md in the root of this project's repository. By participating, you are expected to uphold Qiskit's code of conduct.

We use GitHub issues for tracking requests and bugs.
