Definitions

Pennylane-CalculQuebec is a PennyLane plugin enabling seamless job execution on MonarQ, Calcul Québec’s nonprofit-hosted quantum computer.

It also offers simulation and pre-processing / post-processing capabilities relative to MonarQ quantum computer.

Pennylane is a cross-platform Python library for quantum machine learning, automatic differentiation, and optimization of hybrid quantum-classical computations.

Calcul Quebec is a non-profit organization that regroups universities from the Province of Quebec and provides computing power to research and academia.

Local installation

Pennylane-calculquebec can be installed using pip:

pip install pennylane-calculquebec

Alternatively, you can clone this repo and install the plugin with the following command from the root of the repo:

pip install -e .

Pennylane and other Python dependencies will be installed automatically during the installation process.

Usage

If you need more information about how to use the plugin, you may read the getting-started jupyter notebook.

Running files

The plugin can be used both in python scripts and Jupyter notebooks. To run a script, you can use the following command:

python base_circuit.py

Dependencies

Python modules

Those packages are installed automatically during the plugin installation process and are necessary for the plugin to work. Here are the links to their respective documentation:

• For PennyLane, please refer to the PennyLane documentation.

• Netowkx is a Python graph algorithms library. It is used seemlessly during some of the transpiling steps. Here's the documentation.

• Numpy is a mathematical library that is used heavily by Pennylane, and the plugin. Here's the documentation.

State of the project and known issues

The plugin is currently in its beta phase and provides access to MonarQ directly through API calls. It also contains capabilities for obtaining benchmarks and machine informations. There are also features that let experimented users change the pre-processing / post-processing behaviour of the device, and create custom pre-processing / post processing steps. There is a simulator device which is currently being developed, but the noise model still needs to be tweaked. The placement and routing phases of the transpiler currently chose wires and couplers by prioritizing best fidelities first, but this does not yield optimal results in terms of errors. The unit-test coverage is still not complete.

Future plans

• Have 80 % unit test line coverage for each file in the project
• Integrate circuit paralellization capabilities to run multiple circuits at the same time
• Add new transpiling steps to the device to improve placement, routing, error mitigation and optimization.
• Make the MonarQ simulation device available through qml.device
