hugr-qir 0.0.6

Quantinuum's tool for converting HUGR to QIR

hugr-qir

WARNING: this is a beta version, still under development and not all hugr/guppy programs can be converted

A tool for converting Hierarchical Unified Graph Representation (HUGR, pronounced hugger) formatted quantum programs into QIR format.

Installation

You can install from pypi via pip install hugr-qir.

Usage

Python

Use the function hugr_to_qir from the hugr_to_qir module to convert hugr to qir. By default, some basic validity checks will be run on the generated QIR. These checks can be turned off by passing validate_qir = False.

You can find an example notebook at examples/submit-guppy-h1-h2-via-qir.ipynb showing the conversion and the submission to H1/H2.

CLI

You can use the available cli after installing the python package.

This will generate qir for a given hugr file:

hugr-qir test-file.hugr

Run hugr-qir --help to see the available options.

If you want to generate a hugr file from guppy, you can do this in two steps:

1. add this to the end of your guppy file:

if __name__ == "__main__":
    sys.stdout.buffer.write(guppy.compile(main).package.to_bytes())

2. Generate the hugr file with:

python guppy_examples/quantum-classical-1.py > test-guppy.hugr

Development

#️⃣ Setting up the development environment

The easiest way to setup the development environment is to use the provided devenv.nix file. This will setup a development shell with all the required dependencies.

To use this, you will need to install devenv. Once you have it running, open a shell with:

devenv shell

All the required dependencies should be available. You can automate loading the shell by setting up direnv.

Run tests

You can run the rust test with:

cargo test

You can run the Python test with:

pytest

If you want to update the snapshots you can do that via:

pytest --snapshot-update
