Problem
Current encryption methods rely on computational assumptions that can be broken by advancing algorithms and emerging quantum computers, leaving critical network communications vulnerable. Implementing quantum-secure solutions is difficult because existing quantum hardware is often bulky, expensive, and incompatible with standard telecom infrastructure.
Solution
Xen Quantum offers silicon‑photonics quantum communication modules that perform discrete‑variable quantum key distribution (DV‑QKD) using single photons. The modules generate encryption keys whose security is guaranteed by the laws of physics, and any interception attempt is immediately detectable. By fabricating the devices with CMOS‑compatible silicon photonics, the hardware can be produced at scale, integrated directly into existing telecom rack equipment, and operated within standard fiber‑optic networks. This approach provides a practical, low‑power, and cost‑effective path to quantum‑secure communication for critical data links.
Target Audience
Primary customers are telecom operators, data center operators, and enterprises that require long‑term protection for high‑value communication links, as well as government and defense agencies securing critical networks.
