Projet européen PASQuanS, sélectionné pour la première phase du Quantum Technology Flagship.

Among the quantum technologies that are being developed, quantum simulation aims at addressing questions in fundamental science, materials development, quantum chemistry and real-world problems of high importance in industry. PASQUANS will develop next generation quantum simulation platforms for such applications.

The PASQuanS (Programmable Atomic Large-Scale Quantum Simulation) project funded by the European Commission in the framework of the Flagship on Quantum Technologies builds on the impressive achievements of the most advanced quantum simulation platforms to date, based on atoms and ions. The neutral-atom simulators handle more than 50 cold atoms in optical lattices or arrays of optical tweezers, interacting via either collisional or Rydberg-state-mediated interactions. The ion-trap platform reaches unsurpassed control with up to 20 ions.

By scaling up these platforms towards >1000 atoms/ions, by improving control methods and making these simulators fully programmable, the goal of PASQuanS is to push these already well-advanced platforms far beyond both the state-of-the-art and the reach of classical computation. Full programmability will make it possible to address quantum annealing or optimization problems much sooner than digital quantum computation.  One important aspect will be to demonstrate a quantum advantage for non-trivial problems, paving the way towards practical and industrial applications. PASQuanS will result in modular building blocks for a future generation of quantum simulators.


The PASQuanS project consortium unites five experimental groups with complementary methods to achieve the technological goals, connected with six theoretical teams focusing on certification, control techniques and applications of the programmable platforms, and five industrial partners in charge of the key developments of enabling technologies and possible commercial spin-offs of the project. Possible end-users of these simulators, major industrial actors, are tightly associated with the consortium to help identifying and implementing key applications where quantum simulation provides a competitive advantage.
