Atomic Quantum Computing as a Service

An open and public platform for digital quantum computing based on high quality atomic qubits

Supported by the “Programme d’Investissements d’Avenir” (ANR-21-ESRE-0032) and the “Programme et Equipements Prioritaire de Recherche Quantique” (PEPR) within the French national quantum strategy

Technology behind aQCess

aQCess is powered by arrays of individual atoms trapped by optical tweezers with interactions mediated by highly excited Rydberg states, which is one of the most competitive physical systems for scalable quantum computing.

Neutral atom qubits

The worlds most stable and precise quantum oscillators

Scalable quantum systems

Programmable arrays of atoms trapped and cooled to nearly absolute zero temperature

Unique dual species architecture

Better qubit encoding, storage, processing and readout of quantum information

Highly optimized universal gate set

Native multiqubit gates and fast all-optical qubit control and readout
