Quandela's 12-qubit photonic quantum computer launched in May 2025, delivering 4,000x more computing power than its predecessor. Operates at room temperature in a standard data center rack—no dilution refrigerators required. Available cloud-accessible to over 1,200 researchers and partners in 30 countries. A first integrated version was delivered to EuroHPC/GENCI at CEA's Très Grand Centre de Calcul (TGCC) for national research use. Supports quantum machine learning, materials science, and hybrid HPC-quantum workloads.
Deterministic high-brightness single-photon emitters based on semiconductor quantum dots, developed from CNRS/C2N research. These sources underpin Quandela's photonic qubit generation and are licensed to academic and industrial partners worldwide for quantum communication and computing research. Technically notable for near-unity photon indistinguishability and high extraction efficiency, enabling boson sampling and linear optical quantum computing experiments at the frontier of photonic quantum advantage.
