QSA Technology is developing a new generation of hardware authentication tools, built on the quantum properties of light itself. Our photonic chips have a unique optical fingerprint, enabling a full authentication suite with quantum security credentials.
Trust rooted in hardware, no digital secrets
Scales with number of nodes, not links
Security based on physics, not math
Works on the optical layer, not electronic
Authentication is at the core of all communication: it tells you who you can trust. Yet today’s identities are stored data, keys and certificates that can be stolen or copied without anyone noticing, and quantum computers threaten the signatures they rely on. As long as your link uses light, QSA offers a stronger alternative: an identity that can’t be copied. From quantum key distribution to datacenter links, from satellite communication to edge computing, QSA Technology provides the possession factor ready to face the future.
Every authentication scheme rests on an assumption: that a password stays secret, that a stored key stays protected, that a hard computational problem stays hard. We rest on a different one: that the disordered, sub-wavelength structure inside our photonic chips can’t be cloned. We read that structure not electronically, but in light, faint enough that interrogating it carries the same quantum guarantees that protect quantum communication itself. It’s authentication grounded in physical unclonability, made quantum-secure by the very act of reading it. There’s no digital secret to steal, today or after quantum computers arrive.
Whether you want to test QSA on your own link in a feasibility pilot, co-develop it for your application, or integrate it into your transceivers, terminals or QKD systems: we want to hear from you.
