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 analog computing systems,
  • GPU-accelerated 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). Website coming soon.
