Alpha Release. OpenFermion is an open source library for obtaining and manipulating representations of fermionic systems (including quantum chemistry) for simulation on quantum computers. Cirq is an open source library for writing, manipulating, and optimizing quantum circuits and running them against quantum computers and simulators. OpenFermion-Cirq extends the functionality of OpenFermion by providing routines and tools for using Cirq to compile and compose circuits for quantum simulation algorithms.

Build Status

Getting started

Installing OpenFermion-Cirq requires pip. Make sure that you are using an up-to-date version of it. Once installation is complete, be sure to take a look at our ipython tutorials and code documentation.

Installation

To install the latest PyPI releases as libraries (in user mode):

python -m pip install --user openfermioncirq

Developer install

To install the latest versions of OpenFermion, Cirq and OpenFermion-Cirq (in development mode):

git clone https://github.com/quantumlib/OpenFermion-Cirq
cd OpenFermion-Cirq
python -m pip install -e .

Alpha Disclaimer

OpenFermion-Cirq is currently in alpha. We are still making breaking changes. We will break your code when we make new releases. We recommend that you target a specific version of OpenFermion-Cirq, and periodically bump to the latest release. That way you have control over when a breaking change affects you.
