Our group is interested in the development of new quantum computing algorithms for Computational chemistry. We focus on :

  • algorithmic developments,
  • real-life quantum computer implementations on digital and analogic systems,
  • quantum emulators developments.

The Hyperion-1 Quantum Emulator

  • This  software is able to emulate a quantum computer on classical hardware, conducting exact gate-based quantum simulations on (multi)GPU-accelerated supercomputing systems (in collaboration with Qubit Pharmaceuticals).

OpenVQE: an Open Source Quantum Chemistry Package

  • this package is an Open Source Variational Quantum Eigensolver extension of the Captiva environnent to Quantum Chemistry. It was developed based on the tools of myqlm-fermion. It is freely available on GitHub: [Link] ; see publication [here] (Open Access).
