Coherent and Quside unveil mass-manufacturable quantum entropy source using 6″ VCSEL

COHRCOHR

Coherent and Quside demonstrated a mass-manufacturable quantum entropy source combining Coherent’s 6″ VCSELs with Quside’s QRNG technology to deliver high-quality, verifiable randomness for cryptographic key generation. The real-time entropy verification platform supports scalable deployment in processors, secure elements and hardware roots of trust for quantum-safe security applications.

1. Coherent Schedules Q2 FY2026 Results Release

Coherent Corp. has slated the release of its financial results for the quarter ended December 31, 2025, on Wednesday, February 4, immediately following the New York Stock Exchange close. Management will host a live audio webcast at 4:30 p.m. Eastern Time to discuss performance metrics, order trends and margin outlook. A replay of the presentation will be accessible on the company’s investor relations website within 24 hours, giving analysts and institutional investors an opportunity to review guidance for the second half of fiscal 2026.

2. Photonics West 2026 Showcase Drives Product Pipeline Visibility

At SPIE Photonics West, held January 20–22 in San Francisco, Coherent highlighted 10 new and upgraded products across lasers, advanced materials and beam delivery systems. Notable introductions included an ultra-high thermal conductivity bondable diamond heat spreader for GPU cooling, a compact visible laser with integrated controller for super-resolution microscopy, and a next-generation handheld FieldMax Touch laser power meter capable of 1 kHz pulse energy measurement. Live demonstrations of waste-heat thermoelectric generation and a quantum encryption setup with Quside underscored Coherent’s expanding beachhead in datacenter efficiency and secure communications markets.

3. Breakthrough in Quantum-Safe Encryption with Quside Partnership

In collaboration with quantum specialist Quside, Coherent demonstrated a mass-manufacturable quantum entropy source built around 6-inch VCSEL technology. The runtime-verifiable entropy generator delivers high-quality randomness suitable for cryptographic key generation and hardware roots of trust, positioning Coherent to tap into the emerging $5-billion quantum-safe security market. Commercialization readiness is bolstered by established 6" wafer processing and supply chain resilience, setting the stage for integration into secure elements, processors and network security modules in calendar 2026.
