KETS Quantum Security

KETS Quantum Security develops chip-based quantum security solutions, specifically Quantum Key Distribution (QKD) and Quantum Random Number Generators (QRNG), built on integrated photonics technology to protect against emerging threats from quantum computing and AI. The company's QKD products securely distribute cryptographic keys using the principles of quantum mechanics, providing security based on the laws of physics rather than computational complexity, making it suitable for applications where high security is critical. KETS' QRNG devices generate truly unpredictable random numbers using quantum mechanics, valuable for applications requiring high levels of randomness including password and PIN generation, seeding encryption algorithms (TLS, IPsec, MACsec, and PQC), and statistical simulation. The company's products are ultra-secure, compact, energy efficient, and built to scale for manufacturing, with full-system and sub-system offerings. KETS serves use cases including hardening satellite communications, securing control planes with quantum entropy, protecting internal naval vessel networks (Internal Battleship Network), upgrading telecommunication network connectivity, enabling secure data centre backup, and securing critical infrastructure control systems. The company also provides consultancy and Joint Development Agreement (JDA) services to SMEs. KETS differentiates itself through its integrated photonics approach enabling scalable manufacturing, compact form factor, and low power consumption, and its collaboration with Nokia to scale commercial QKD globally. Founded in 2016 and headquartered in Bristol, United Kingdom, KETS Quantum Security has raised approximately $4.4 million in a Series A round backed by Quantonation, x Systems, Speedinvest, MSM, Seraphim Space Camp, Audacia, MK Venture Capital, Seraphim, Aken Capital, 2050 Capital, Generation Space, First Derivatives, University of Bristol, British Business Bank, and Evenlode Investment.
