Extension for pytket, providing access to AQT backends

Project description

Pytket Extensions

This repository contains the pytket-aqt extension, using Quantinuum's pytket quantum SDK.


Pytket is a python module for interfacing with tket, a quantum computing toolkit and optimisation compiler developed by Quantinuum.

pytket-aqt is an extension to pytket that allows pytket circuits to be executed on AQT's quantum devices and simulators.

Getting started

pytket-aqt is available for Python 3.10 and 3.11, on Linux, MacOS and Windows. To install, run:

pip install pytket-aqt

This will install pytket if it isn't already installed, and add new classes and methods into the pytket.extensions namespace.

Bugs, support and feature requests

Please file bugs and feature requests on the Github issue tracker.

There is also a Slack channel for discussion and support. Click here to join.


To install an extension in editable mode, simply change to its subdirectory within the modules directory, and run:

pip install -e .


Nox is used to automate various development tasks running in isolated python environments. The following nox sessions are provided:

  • test: run tests for all supported python versions
  • lint: run black and pylint for all supported python versions
  • type_check: run mypy for all supported python versions

To run a session, install the nox command (e.g., using pipx) and run:

nox -s <session_name>

To save time, reuse the session virtual environment using the -r option, i.e. nox -rs <session_name>. The checks are designed to conform to


Pre-commit can be used to run a configured set of git pre-commit hooks before each commit. This is recommended. To set up the pre-commit hooks, install pre-commit (e.g., using pipx) and run:

pre-commit install

Afterwards the pre-configured hooks will run automatically before each commit. The commit will be rejected if the hooks find errors. Some hooks will correct formatting issues automatically (but will still reject the commit, so that the git commit command will need to be repeated).

Note that some pre-commit hooks require that nox is installed (e.g., using pipx)


Pull requests are welcome. To make a PR, first fork the repo, make your proposed changes on the develop branch, and open a PR from your fork. If it passes tests and is accepted after review, it will be merged in.

Code style


All code should be formatted using black, with default options. This is checked on the CI. The CI is currently using version 20.8b1.


We use pylint on the CI to check compliance with a set of style requirements (listed in .pylintrc). You should run pylint over any changed files before submitting a PR, to catch any issues.

If you have nox installed (see Noxfile) use nox -rs lint to run black and pylint

Type annotation

On the CI, mypy is used as a static type checker and all submissions must pass its checks. You should therefore run mypy locally on any changed files before submitting a PR. Because of the way extension modules embed themselves into the pytket namespace this is a little complicated, but it should be sufficient to run the script modules/mypy-check (passing as a single argument the root directory of the module to test). The script requires mypy 0.800 or above.

If you have nox installed (see Noxfile) use nox -rs type_check to run mypy


If you have nox installed (see Noxfile) use nox -rs test to run all tests.

Otherwise, to run the tests for a module:

  1. cd into that module's tests directory;
  2. ensure you have installed pytest, hypothesis, and any modules listed in the test-requirements.txt file (all via pip);
  3. run pytest.

When adding a new feature, please add a test for it. When fixing a bug, please add a test that demonstrates the fix.
