PASQuanS2 released a new interview with CNRS researcher Antoine Browaeys on the state of neutral-atom quantum simulation and the project’s priorities. Building on PASQuanS1, PASQuanS2 focuses on two goals: improving platform performance—more atoms, higher fidelities, and greater programmability—and benchmarking results against leading classical simulations to assess potential quantum advantage.

“The idea is to know whether the machine performs well enough that there is no classical way to simulate it,” Browaeys says, noting the team’s emphasis on noise calibration, correlation measurements, and co-design with theorists. He also highlights the role of industry partners—from laser and optics providers to software, hardware and HPC teams—who help prototype, test and iterate rapidly.

While applications such as materials and chemistry remain longer-term, certain optimisation problems may yield earlier benefits, though the field continues to debate scope and impact. Browaeys stresses that academic research remains vital, calling quantum simulation a long-term process requiring sustained support.
