Coherent Corp. and Quside demonstrated a hardware-based quantum entropy source designed for mass manufacturing, targeting secure key generation and quantum-safe encryption. The companies validated that a single vertical-cavity surface-emitting laser (VCSEL) can generate fast, observable, and verifiable quantum randomness suitable for deployment at scale.
The demonstration integrates Coherent’s 6-inch VCSEL manufacturing platform with Quside’s quantum random number generation (QRNG) technology. Runtime entropy verification from a single VCSEL enables cryptographic-grade randomness without external optical assemblies, supporting integration into processors, secure elements, and hardware roots of trust. The approach aims to move quantum entropy from niche security modules into mainstream silicon platforms.
Coherent and Quside plan to present a live demonstration and development kits at Photonics West 2026. The companies say the design aligns with established production processes and cost structures, positioning the technology for high-volume deployment across data centers, communications systems, and other security-sensitive infrastructure.

“VCSEL technology has already demonstrated its reliability and scalability across datacenters, sensing, and high-volume optical systems,” said Giovanni Barbarossa, chief strategy officer at Coherent. “This collaboration shows how mature photonic manufacturing platforms can enable entirely new security functions while meeting the cost, reliability, and scale requirements needed for broad market adoption.”
🌐 Analysis
The work reflects growing industry focus on hardware-anchored entropy as post-quantum cryptography gains urgency, alongside standards efforts to harden roots of trust against side-channel and supply-chain risks. Coherent’s use of a volume VCSEL process and Quside’s emphasis on local verification distinguish this approach from discrete QRNG modules, while competitors across silicon security and photonics continue to explore integrated entropy sources tied to processors and secure enclaves.
