SAXONBURG, Pa., Jan. 20, 2026 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, and Quside, a quantum technology company, have reached a major milestone in hardware-based security with the successful demonstration of a mass manufacturable quantum entropy source. This achievement shows that fast, verifiable quantum entropy – an essential foundation for secure digital systems – can be embedded at scale, supporting next-generation security architectures across a wide range of applications. The solution relies on Coherent's vertical cavity surface emitting laser (VCSEL) manufactured at scale on 6” and Quside's quantum random number generation technology. For the first time, runtime entropy verification from a single VCSEL delivers high-quality, observable randomness suitable for cryptographic key generation, secure communications, and emerging quantum-safe and crypto-agile systems. Therefore, quantum-grade security primitives can now move beyond niche deplo
