pytket is a python module for interfacing with CQC t|ket>, a set of quantum programming tools. We currently support circuits and device architectures from Google Cirq, IBM Qiskit, Pyzx, ProjectQ and Rigetti pyQuil, allowing the t|ket> tools to be used in conjunction with projects on these platforms.

Getting Started

pytket is available for python3.6 or higher, on Linux and MacOS. To install, run

pip install pytket

Note: attempting to install from source will not set up the required binaries for the t|ket> compiler, so we recommend the PyPI installation.

See the Getting Started page for a quick introduction to using pytket.

To get more in depth on features, see the examples.


To use pytket in conjunction with other platforms you must download an additional separate module for each. This can be done from pip, or from source, as they binaries are included with the core pytket package.

For each subpackage:

Qiskit: pip install pytket-qiskit

Cirq: pip install pytket-cirq

PyQuil: pip install pytket-pyquil

ProjectQ: pip install pytket-projectq

PyZX: pip install pytket-pyzx

Note:this will need a separate install of pyzx from source.
