8 terms

vertical cavity surface emitting laser technical

"The solution relies on Coherent’s vertical cavity surface emitting laser (VCSEL)"

A vertical cavity surface emitting laser (VCSEL) is a small semiconductor device that produces a focused beam of light straight out of the chip surface, like a tiny LED that acts as a precise flashlight. Investors care because VCSELs are key components in high-volume products and systems—such as optical communications, motion sensing, and facial recognition—so changes in demand, supply capacity, or manufacturing costs can noticeably affect revenue, margins, and growth prospects for companies that make or use them.

vcsel technical

"from a single VCSEL delivers high-quality, observable randomness"

A VCSEL is a tiny semiconductor laser that emits light straight out of the surface of a chip, like a miniature, very precise flashlight built into an electronic component. Investors care because VCSELs are key parts in optical communication, sensors, and proximity or gesture controls—products with growing demand—so changes in VCSEL supply, cost or adoption can affect a maker’s sales, margins and the competitive position of companies that rely on them.

quantum entropy medical

"mass manufacturable quantum entropy source"

Quantum entropy measures how much uncertainty or disorder is present in a quantum system — think of it like how mixed up the pieces are in a puzzle so you can’t predict their exact arrangement. For investors, it matters because lower entropy often means a device or protocol can store, transmit or protect quantum information more reliably, influencing the performance, error rates and commercial potential of quantum computing and encryption products.

quantum random number generation technical

"and Quside’s quantum random number generation technology"

Quantum random number generation uses laws of quantum physics to produce sequences of unpredictable numbers that cannot be predicted or reproduced, unlike algorithm-generated pseudo-random numbers. For investors, it matters because truly random numbers strengthen encryption, secure financial transactions and communications, and can be a selling point for technology and service providers in cybersecurity and fintech—similar to replacing a predictable lock with a lock that cannot be copied.

cryptographic key generation technical

"suitable for cryptographic key generation, secure communications"

Cryptographic key generation is the process of creating the unique digital 'keys' that lock and unlock encrypted data and verify digital identities, similar to making a matched pair of locks and keys for secure access. For investors, strong key generation matters because it underpins a company’s data security, transactional integrity and regulatory compliance; weak or mishandled keys can lead to breaches, loss of customer trust, legal penalties and financial harm.

quantum-safe technical

"emerging quantum-safe and crypto-agile systems"

Quantum-safe describes encryption methods, protocols and systems designed to remain secure even if powerful quantum computers exist; think of them as locks built to resist a future master key. For investors, quantum-safe technology matters because it protects sensitive data and intellectual property, reduces future compliance and replacement costs, and can lower the risk of disruptive cyber losses or legal liabilities as quantum computing advances.

crypto-agile technical

"emerging quantum-safe and crypto-agile systems."

Crypto-agile describes a person, team, or company that can quickly adapt processes, technology, and strategy to changes in cryptocurrency markets, rules, or tools. For investors it matters because being crypto-agile helps protect value and seize opportunities when prices, regulations, or platforms shift—like a small boat trimming its sails to stay stable and move fast in shifting winds. It emphasizes flexibility, risk controls, and fast decision-making.

hardware roots of trust technical

"processors, secure elements, and hardware roots of trust."

A hardware root of trust is a small, dedicated chip or hardware function that anchors a device’s security by holding secret keys and performing basic checks that other software relies on. Think of it as a locked vault or foundation piece that proves a device’s identity and ensures software hasn’t been tampered with. For investors, strong hardware roots of trust lower the risk of costly breaches, enable secure services and regulatory compliance, and can be a competitive advantage for products that handle sensitive data.

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 deployments into mainstream processors, secure elements, and hardware roots of trust.

“VCSEL technology has already demonstrated its reliability and scalability across datacenters, sensing, and high-volume optical systems,” said Dr. Giovanni Barbarossa, Chief Strategy Officer at Coherent Corp. “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.”

“Security systems are only as strong as the randomness they rely on,” said Dr. Carlos Abellán, Chief Executive Officer and co-founder of Quside. “What makes this milestone unique is not only that the entropy is generated through quantum processes, but that it is fast, verifiable, and mass manufacturable by relying on volume proven 6” VCSEL production. This moves locally verified quantum entropy technology into practical, deployable infrastructure.”

At Photonics West 2026 in San Francisco, Coherent and Quside will present a live demonstration of the technology alongside development kits. Attendees will have the opportunity to explore how the solution can be integrated into next-generation secure designs, from silicon to system level, to meet growing demand in entropy generation and verification.

With manufacturing-ready components and established production processes, Coherent and Quside are paving the way towards high-volume commercial deployment of quantum entropy solutions designed for real-world, large-scale secure infrastructure.
