PASQuanS2 (Programmable Atomic Large-Scale Quantum Simulation) has the goal of building a quantum simulator capable of handling simulations of up to 10,000 atoms. It is a follow-on to the previous European Flagship program PASQuanS which initially explored the concept of quantum simulation with smaller arrays. Although a quantum simulator is not as general purpose as a full-fledged programmable quantum processor, it can be very effective for solving certain computation problems beyond the capability of a classical processor, particularly for problems involving quantum chemistry.

The project will be led by the German Max Planck Institute of Quantum Optics and this next phase will last 3.5 years (April 2023 – September 2026). It will include 25 academic and technology partners from Austria, France, Germany, Italy, Slovenia and Spain. The goal of phase, also called PASQuanS2.1 will be to develop the hardware and software needed to support simulation of up to 2,000 atoms with a roadmap to extend the technology further. It is expected that this phase will have a follow-on program, PASQuanS2.2, for another 3.5 years to develop a system capable of the 10,000 atoms.
