Q-CTRL Python Cirq

The aim of the Q-CTRL Cirq Adapter package is to provide export functions allowing users to deploy established error-robust quantum control protocols from the open literature and defined in Q-CTRL Open Controls on Google quantum devices and simulators.

Anyone interested in quantum control is welcome to contribute to this project.

Installation

Q-CTRL Cirq Adapter can be installed through pip or from source. We recommend the pip distribution to get the most recent stable release. If you want the latest features then install from source.

Requirements

To use Q-CTRL Cirq Adapter you will need an installation of Python. We recommend using the Anaconda distribution of Python. Anaconda includes standard numerical and scientific Python packages which are optimally compiled for your machine. Follow the Anaconda Installation instructions and consult the Anaconda User guide to get started.

We use interactive jupyter notebooks for our usage examples. The Anaconda python distribution comes with editors for these files, or you can install the jupyter notebook editor on its own.

Using PyPi

Use pip to install the latest version of Q-CTRL Cirq Adapter.

pip install qctrl-cirq

From Source

The source code is hosted on Github. The repository can be cloned using

git clone git@github.com:qctrl/python-cirq.git

Once the clone is complete, you have two options:

1. Using setup.py

   cd python-cirq
   python setup.py develop

   Note: We recommend installing using develop to point your installation at the source code in the directory where you cloned the repository.

2. Using Poetry

   cd python-cirq
   ./setup-poetry.sh

   Note: if you are on Windows, you'll need to install Poetry manually, and use:

   cd python-cirq
   poetry install

Once installed via one of the above methods, test your installation by running pytest in the python-cirq directory.

pytest

Usage

See the Jupyter notebooks.

Building documentation

Documentation generation relies on Sphinx.

To build locally:

1. Ensure you have used one of the install options above.

2. Execute the make file from the docs directory:

   If using Poetry:

   cd docs
   poetry run make html

   If using setuptools:

   cd docs
   # Activate your virtual environment if required
   make html

The generated HTML will appear in the docs/_build/html directory.
