PASQAL designs and develops Quantum Processing Units and dedicated software tools. These innovative processors address applications which are out of the reach of the most powerful existing supercomputers, encompassing real-world challenges as well as fundamental science. As they are very low energy intensive, they will significantly contribute to reduce the carbon footprint of the computing industry.

PASQAL has partnerships with key users in the fields of energy, IT, finance, drug and chemical design, automotive… The maturity and potential of our technology and the quality of our scientific team has been rewarded several times at French, European as well as global levels.

Our technology builds upon considerable knowledge accumulated over decades by the Institut d’Optique near Paris (IOGS / CNRS); it makes the best of numerous recent achievements in laser cooling of atoms, opto-electronics, vacuum and detection systems. Based in Massy and Palaiseau, at the heart of the quantum ecosystem south of Paris, PASQAL is funded by Quantonation, a VC fund focusing on Quantum Technologies, and is attracting world-class investors.

Joining PASQAL is an opportunity to contribute to the rapid development of a Deep-Tech startup at the forefront of the second Quantum Revolution.
