pytket-cirq

Cirq is a python library for producing quantum circuits and running them on simulators and physical quantum devices.

pytket-cirq is an extension to pytket that allows conversion to and from Cirq representations.

pytket-cirq is available for Python 3.11, 3.12 and 3.13, on Linux, MacOS and Windows. To install, run:

pip install pytket-cirq
