Co-founded in 2017 by Pascale Senellart (research director at the Center for Nanoscience and Nanotechnology, a CNRS and University of Paris-Saclay laboratory and 2014 CNRS silver medalist), Valérian Giesz (PhD engineer in optics) and Niccolo Somaschi (Ph.D. in semiconductor nanotechnology), Quandela is known for being the originator of Prometheus, the world’s first photonic qubit generator with broad application domains including quantum cryptography, quantum computation or quantum sensors.

Quandela’s technology, the result of more than 20 years of research at the Centre for Nanoscience and Nanotechnology, is unique in the world. It has been published several times in peer-reviewed journals such as Nature and Physical Review Letters.

Based on this technology, the Quandela team has progressively developed an entanglement system based on a chain of single photons contained in an optical fibre loop. The assembly of different components already offered to the market by Quandela (eDelight, 6-DMX, QShaper, QFiber, …) has allowed the creation of a prototype quantum computer based on a high flux of single and indistinguishable photons for demanding quantum research. From 2022, this opens up the possibility of putting this type of machine online (“cloud”) to promote broad access to research and its computing resources.
