KETS Kore
A family of chip-based QKD transmitter and receiver components designed for system integrators to embed quantum key distribution into their own products. The range spans from bare packaged QKD chips (for teams with RF hardware expertise), through chip subsystems with integrated analogue circuitry and fibre/RF interfaces, up to advanced chip subsystems with onboard digital processing and a PCIe interface accessible via the KETS software API. A complete embeddable QKD solution is also available, providing a self-contained Tx/Rx system accessed via ETSI014, SNMP or proprietary interface. Primary use cases include hardening satellite communications, securing SDN control planes in telecoms networks and protecting internal networks on naval vessels.
Quantum Key Distribution (QKD)
A full QKD product line for securing communications links in telecoms networks, data centre backup connections and critical infrastructure control systems. Security is rooted in the laws of physics rather than computational assumptions, meaning encryption keys are generated and distributed in a way that makes eavesdropping detectable. Designed for deployment alongside standard fibre infrastructure, the product targets providers looking to achieve quantum-safe standards ahead of Q-Day.
Quantum Random Number Generator (QRNG)
Hardware devices that generate truly random numbers from quantum phenomena, available as packaged QRNG chips, a Quantum Entropy Board and a QRNG PCIe card. Unlike pseudo-random number generators, the randomness cannot be replicated or predicted. Applications include seeding TLS, IPsec, MACsec and post-quantum cryptography algorithms, generating random passwords and PINs, and powering statistical simulations in finance, clinical research and scientific modelling.
About
KETS Quantum Security is a Bristol-based quantum security company, founded in 2016 as a spinout from the Quantum Engineering Technology Laboratories at the University of Bristol. Founded by Philip Sibson, Jake Kennard and Chris Erven, the company develops chip-based hardware that uses quantum mechanics to secure communications — primarily Quantum Key Distribution (QKD) and Quantum Random Number Generation (QRNG) products.
