OpenFermion-ProjectQ (Deprecated) Documentation Status

OpenFermion is an open source package for compiling and analyzing quantum algorithms that simulate fermionic systems. This plugin library allows the circuit simulation and compilation package ProjectQ to interface with OpenFermion. However, OpenFermion-ProjectQ is now archived and deprecated since it is NO LONGER MAINTAINED. If you are interested in maintaining the package and qualified to do so, please contact us.

Getting started

Installing OpenFermion-ProjectQ 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 the ipython notebook demo as well as our detailed code documentation.

Developer install

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

git clone
cd OpenFermion-ProjectQ
python -m pip install -e .

Library install

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

python -m pip install --user openfermionprojectq

How to contribute

This package is deprecated and no longer accepting contributions. However, if you are interested in maintaining the package and qualified to do so, please contact us. We would be happy to transfer the repository to responsible owners if there is interest in continuing development.
