aQCess — Atomic Quantum Computing as a Service
France’s first open and public platform for digital quantum computing on high-quality atomic qubits.
2021–2029 €8.85M total €5.7M Unistra Coordinator
aQCess is powered by arrays of individual atoms trapped by optical tweezers, with interactions mediated by highly excited Rydberg states — one of the most competitive physical systems for scalable quantum computing. The platform hosts over 400 individually controlled ytterbium qubits for universal quantum computing, and is open to academic, industry, and educational partners.
What makes aQCess distinctive
- Full-stack digital platform built around ytterbium-171 atoms — natures best qubits.
- Dual-qubit architecture for robust qubit encoding, storage, processing, and readout.
- Highly optimised universal gate set with native multiqubit gates and fast all-optical control and readout.
- Open access for research, industry trials, and quantum workforce training across seven research institutes, five graduate programmes, and four international partners.
Use cases
Quantum chemistry · material discovery · fundamental physics · optimisation · machine learning.
