Q-CTRL Open Controls
Q-CTRL Open Controls is an open-source Python package that makes it easy to create and deploy established error-robust quantum control protocols from the open literature. The aim of the package is to be the most comprehensive library of published and tested quantum control techniques developed by the community, with easy to use export functions allowing users to deploy these controls on:
- Custom quantum hardware
- Publicly available cloud quantum computers
- The Q-CTRL product suite
Anyone interested in quantum control is welcome to contribute to this project.
Q-CTRL Open Controls 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.
To use Q-CTRL Open Controls 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.
pip to install the latest version of Q-CTRL Open Controls.
pip install qctrl-open-controls
The source code is hosted on GitHub. The repository can be cloned using
git clone email@example.com:qctrl/open-controls.git
Once the clone is complete, you have two options:
Follow the instructions from the Poetry documentation to install Poetry.
After you have installed Poetry, use:
cd open-controls poetry install
cd open-controls poetry export --dev -f requirements.txt --output requirements.txt --without-hashes pip install -r requirements.txt pip install -e . rm requirements.txt
Once installed via one of the above methods, test your installation by running
pytest in the
For general guidelines, see Contributing.
To build it locally:
Ensure you have used one of the install options above.
Execute the make file from the docs directory:
If using Poetry:
cd docs poetry run make html
If using pip:
cd docs # Activate your virtual environment if required make html
The generated HTML will appear in the
Formatting, linting, and static analysis
Code is formatted, linted and checked using the following tools:
These checks are run on all code merged to master, and may also be run locally from the open-controls directory:
pip install black isort mypy pylint
isort --check .
black --check .
Note that you can speed up the execution of Pylint by running it in the parallel mode with the
pylint -j 0 .. See the official documentation for details.
Black and isort, in addition to checking code, can also automatically apply fixes. To fix all code in the open-controls tree, run:
You can also run these checks only in the files that you changed by using the
pre-commit tool. To use it, run:
pip install pre-commit
With this, the checks will run every time that you commit code with
git commit. If you prefer to run the checks every time that you push changes instead of when you commit changes, use
pre-commit install -t pre-push.
If you no longer wish to use
pre-commit, you can uninstall it by running
pre-commit uninstall in the
open-controls directory (or by running
pre-commit uninstall -t pre-push, if you used the pre-push hooks).
