parityos-tket 0.1.0

Tket extension for ParityOS

ParityOS Tket

ParityOS extension adding an interface to tket.

Installation

It is recommended to install this package in a separate Python virtual environment. For example:

# To create a standard Python virtual environment:
python -m venv my_new_venv && source my_new_venv/bin/activate
# Alternatively, to create a Anaconda/Miniconda environment:
conda create --name my_new_conda_env python=<version> && conda activate my_new_conda_env
# or a pyenv environment
pyenv virtualenv <version> my_new_venv && pyenv activate my_new_venv
# or a uv managed environment
uv venv -p <version>

where <version> is a python version and one of [3.11, 3.12, 3.13].

After activating the virtual environment, install via your favorite package manager, e.g.:

# using pip
pip install parityos-tket
# using uv
uv pip install parityos-tket

Exporter

parityos-tket offers an exporter of ParityOS to tket quantum circuits.
