About

Xen Quantum is a Cambridge spin-out from Wave Photonics building chip-based Quantum Key Distribution (QKD) modules in silicon photonics. Its approach is relentless simplification of QKD at every level, from protocol and architecture to components and manufacturing, fabricated on the same mature silicon photonics processes that already make photonic chips cheap and scalable. QKD is the one known technology whose security does not rest on computational assumptions, so it cannot be broken by faster computers or better algorithms, including harvest-now-decrypt-later attacks. Today's QKD systems remain too complex to manufacture, deploy, and integrate into existing networks at scale, and that manufacturing barrier is the problem Xen Quantum targets. The company was co-founded by Davide Scalcon, with the idea taking shape during the founders' time at Wave Photonics. Early backers include Cambridge Enterprise, Parkwalk, QAI Ventures, Silicon Catalyst.UK, and Berkeley SkyDeck.
