Quantum Dice

Quantum Dice is an Oxford University spinout pioneering quantum random number generation (QRNG) technology for cybersecurity and, more recently, probabilistic computing. Founded in 2020 by five Oxford graduates through the inaugural StEP Ignite student entrepreneurship programme, the company was built around a patent developed at Oxford’s renowned quantum optics laboratory. At its core, Quantum Dice’s technology solves a problem that underpins the security of virtually every digital system in the world: the need for genuinely random numbers to generate unbreakable encryption keys. Conventional random number generators can be compromised; quantum randomness, derived from the fundamental unpredictability of quantum mechanics, cannot.

Quantum Dice’s flagship QRNG products use its proprietary DISC protocol (Device-Independent Self-Certification) to continuously monitor and verify the quality of the randomness being generated in real time — automatically adjusting for any environmental noise or hardware degradation. This self-certifying property, unique to Quantum Dice, gives users provable assurance that their encryption keys meet a minimum guaranteed quality level at all times. The company’s APEX device generates random numbers at 7.5 Gbps, eight times faster than its closest market competitors, making it the world’s fastest QRNG and suitable for data centres, telecoms hubs, and enterprise cybersecurity applications. The company has since expanded its technology stack to include ORBIT, a photonics-powered probabilistic processing unit for NP-hard computational optimisation problems.

Quantum Dice raised £4.1 million to commercialise its ORBIT technology and expand its QRNG business, following partnerships with HSBC, the Science and Technology Facilities Council’s Hartree Centre, Astute Group, and SCI Semiconductor, as well as a €2 million grant from the European Innovation Council. The company has been awarded a World Economic Forum Quantum for Society Challenge win and has supplied technology to satellite and defence applications alongside its enterprise cybersecurity client base.
