A collection of quantum algorithms built using the Rigetti Forest platform. Grove is licensed under the Apache 2.0 license.
Grove currently includes:
- The Variational-Quantum-Eigensolver (VQE)
- The Quantum Approximate Optimization Algorithm (QAOA)
- The Quantum Fourier Transform (QFT)
- Phase Estimation Algorithm
Features in the alpha package are considered experimental.
Documentation is hosted at http://grove-docs.readthedocs.io/en/latest/
You can install Grove directly from the Python package manager pip using:
pip install quantum-grove
To instead install Grove from source, clone this repository, cd into it, and run:
pip install -e .
This will install Grove’s dependencies if you do not already have them. However, you will still need to install pyQuil and set up a connection to the Rigetti Forest (see below). To enable the tomography module, you will also have to install qutip and cvxpy, see below for more details.
Grove also requires the Python library for Quil, called pyQuil.
You can install pyQuil directly from the Python package manager pip using:
pip install pyquil
To instead install pyQuil from source, clone the
pyQuil GitHub repository,
cd into it, and run:
pip install -e .
You will need to make sure that your pyQuil installation is properly configured to run with a quantum virtual machine (QVM) or real quantum processor (QPU) hosted on the Rigetti Forest, which requires an API key. See the pyQuil docs for instructions on how to do this.
Quantum tomography relies on the external packages qutip and and cvxpy, which can be somewhat tricky to install.
You can first attempt to just run
pip install -r requirements.txt
pip install -r optional-requirements.txt
pip install quantum-grove
If the installation of the optional requirements fails, you can manually install the individual packages as
pip install cython==0.24.1 scs==1.2.6
pip install qutip==4.1 cvxpy
These are not the most recent versions but they are the only ones that have consistently worked for us across different platforms and python versions.
For Windows users: Both qutip and cvxpy are fairly tricky to
install under windows and we therefore recommend using Anaconda's
conda package manager to install these first and then pip
to install quantum-grove.
We use sphinx to build the documentation. To do this, navigate into Grove's top-level directory and run:
sphinx-build -b html docs/ docs/_build
To view the docs navigate to the newly-created docs/_build directory and open
the index.html file in a browser. Note that we use the Read the Docs theme for
our documentation, so this may need to be installed using pip install sphinx_rtd_theme.
We use tox and pytest for testing. Tests can be executed from the top-level directory by simply running:
tox
The setup is currently testing Python 2.7 and Python 3.6.
