Quantum Dice

Quantum Dice is an Oxford University spin-out developing high-speed, self-certifying quantum random number generators (QRNGs) for cybersecurity applications. The company's core innovation is its patented DISC™ (Source-Device Independent Self-Certification) protocol, which continuously verifies the quantum integrity of the numbers it generates in real time — a capability no classical random number generator can match and one that is critical for encryption systems securing everything from data centres to satellite communications.

The company was founded in 2019 when five Oxford students — Ramy Shelbaya, Wenmiao Yu, Zhanet Zaharieva, Marko Mayr and George Dunlop — met through Oxford University's inaugural Student Entrepreneurs Programme. They recognised the commercial potential of a world-record-breaking QRNG prototype developed in Oxford's Quantum Optics research group and set about building a company to bring it to market. The company is backed by Elaia Partners, IP Group and the UK Innovation and Science Seed Fund.

Quantum Dice's ORBIT probabilistic computing platform extends its scope beyond QRNGs toward probabilistic computing workloads that are computationally expensive on conventional hardware, including optimisation problems in logistics, finance and AI inference. Its first-generation Lagrange 0 system operates at room temperature and integrates with existing semiconductor infrastructure, removing the cryogenic barriers that make fully quantum systems impractical for near-term commercial deployment.

In 2025, Quantum Dice was selected as one of only 40 deep-tech startups from over 1,000 applicants to receive a £1.8m grant from the European Innovation Council Accelerator — one of just three UK companies in the cohort. The company was also named a winner of the World Economic Forum's Quantum for Society Challenge and has established a partnership with the STFC Hartree Centre to explore industrial deployment pathways for its probabilistic computing platform.
