What Xen Quantum does

Xen Quantum develops silicon-photonics-based quantum key distribution (QKD) modules for secure communications. The company's core product is a hardware module that uses discrete-variable QKD, encoding information on individual photons to generate encryption keys whose security is guaranteed by the laws of physics rather than computational assumptions. The architecture is patented and reduces system complexity at the optical and electronic levels, enabling CMOS-compatible fabrication, room-temperature operation, and integration into existing telecom rack equipment and fibre-optic infrastructure. Supporting components include photonic integrated circuits designed for wafer-scale volume manufacturing and compact photonic subsystems driven by practical electronics.

Core offering

Xen Quantum develops and sells silicon-photonics-based quantum communication modules that perform discrete-variable quantum key distribution (DV-QKD) to generate provably secure encryption keys for critical networks. The modules use a patented simplified architecture compatible with CMOS fabrication, integrate directly into telecom rack equipment and existing fibre-optic infrastructure, and operate at room temperature without cryogenic cooling, enabling scalable deployment for telecom carriers, government networks, and financial institutions.

Product overview

Xen Quantum offers a unified quantum communication security platform centered on silicon-photonics-based quantum communication modules. The core product is their QKD (Quantum Key Distribution) system using discrete-variable encoding on individual photons. Supporting components include photonic integrated circuits (PICs) designed for volume manufacturing with wafer-scale fabrication, and room-temperature photonic subsystems driven by compact electronics. The architecture is designed for simplified integration with existing telecom rack equipment and fiber-optic infrastructure. The company's proprietary patented architecture reduces system complexity at optical and electronic levels, resulting in fewer failure points and lower power consumption suitable for CMOS-compatible fabrication.
