ParityOS Qrisp

ParityOS extension adding an interface to Qrisp.

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-qrisp
# using uv
uv pip install parityos-qrisp

Exporter

parityos-qrisp offers an exporter of ParityOS quantum circuits to Qrisp quantum circuits.

Basic usage

In the following you find a basic usage of the exporter:

from parityos.operators.circuit import Circuit
from parityos.operators.elementary_operator import H
from parityos_qrisp.exporter import export_parityos_to_qrisp

#      ┌───┐┌─┐
#   0: ┤ H ├┤M├──────

parityos_circuit = Circuit(
    [
        H(q(0)),
        H(q(1)),
        H(q(2)),
    ]
).measure_all()

qrisp_circuit = export_parityos_to_qrisp(parityos_circuit)

Unsupported features

Currently, parityos-qrisp cannot export the following circuits:

• Circuits containing conditional operators
• Circuits containing general rotation operators
• Circuits containing measurements in Y
• Circuits containing the following gates (including their controlled versions): ISwap, ECR, RYY, RXZ, RExchangeTerm
