About us

My Cryo Firm, a French specialist in cryogenic systems

My Cryo Firm® is Pasqal’s dedicated cryogenics brand, specializing in the design, manufacture and commercialization of closed-cycle cryostats and related technologies.
‍
Alongside its commercial product activity, the My Cryo Firm team contributes cryogenic engineering expertise to Pasqal’s research and development of next-generation neutral-atom quantum processors.

This expertise has contributed to several major scientific developments, including single-atom trapping lifetimes of up to 6,000 seconds and the rearrangement of individual atoms in a 2,000-site optical-tweezer array at cryogenic temperatures. More recently, it has also supported Pasqal’s demonstration of a defect-free 1,024-atom register in a 4 K environment.

Our story

My Cryo Firm was founded in 2013 by Julien Paris, a cryogenic engineer, with the ambition to design closed-cycle cryostats combining performance, reliability and experimental flexibility. From its early systems to the OptiDry platform, My Cryo Firm has focused on cryogenic solutions for demanding research environments, including optics, transport measurements, metrology and quantum technologies. The company grew around a practical engineering approach: working closely with researchers to adapt each cryostat to the constraints of their experiment.

In 2022, My Cryo Firm joined Pasqal while continuing to develop and commercialize closed-cycle cryostats under its own trademark. Its cryogenic expertise now also contributes to Pasqal’s R&D roadmap for next-generation neutral-atom quantum processors, where low-temperature environments can play a key role in improving vacuum quality, extending atom lifetimes and scaling toward large atom registers.
‍
Today, the My Cryo Firm team is based in Joinville-le-Pont, near Paris, and brings together expertise in cryogenic engineering, mechanical design, assembly, testing and customer support.
