aQCess

Recent advances in our ability to prepare and control isolated quantum objects will enable the resolution of important computational problems that currently cannot be solved even with the most powerful classical computers. aQCess – Atomic Quantum Computing as a Service – is a public platform dedicated to quantum computing, led by the University of Strasbourg and supported by the EquipEx+ program and the PEPR Quantique as part of the national strategy for quantum technologies. The project brings together 18 partners who are developing scientifically and industrially relevant use cases, to ensure that the platform will be widely used for multidisciplinary research and teaching covering chemistry, materials science, physics, mathematics and computer science.

The technology uses ultra-cold Rydberg atoms, which currently represent one of the most promising physical systems for quantum simulation and computation, with a digital quantum processor of 400 individually controllable, high-quality atomic qubits.

aQCess will be open to users as a training, testing and development platform for a growing number of start-ups and established companies investing in quantum technologies. It will make a major contribution to training tomorrow’s scientists and engineers with the skills needed in quantum science and technology and its applications.

Currently in the construction phase, the main components of the quantum processor have already been delivered, while assembly of the system continues, with the start of operations scheduled for late 2026.
