Fraunhofer Institute for Photonic Microsystems IPMS has unveils Q‑Dice, a high‑performance quantum random number generator (QRNG) that creates randomness based on quantum vacuum fluctuations. The system delivers true random numbers at bit rates exceeding 4Gbit/s based on intrinsically random and uncontrollable quantum effects. True randomness is a fundamental requirement for modern cryptographic and security systems, where weak or predictable random number generators can introduce vulnerabilities in encryption and authentication.
“With Q-Dice, we make high-quality quantum randomness practically usable and accessible. Whether as a robust 19-inch rack system integrated into your own infrastructure or via our online Entropy-as-a-Service platform, we are removing the barriers to adopting quantum-level security,” said Dr. Alexander Noack (pictured with the QRNG R19” demonstrator), Division Director Data Communication & Computing at Fraunhofer IPMS.
Unlike existing approaches, Q-Dice does not rely on potentially vulnerable algorithms and enables significantly higher data rates, making it particularly well suited for security-critical applications. The quality of the generated randomness has been validated through established and internationally recognized testing frameworks, including BSI AIS 20/31 and the NIST SP 800-22 test suite.
By measuring inherently unpredictable quantum vacuum fluctuations, Q‑Dice generates quantum entropy suitable for a wide range of applications, including secure communication, data encryption (e.g., via QKD or PQC), authentication and access management, as well as high‑scale simulation. The system is designed with a strong focus on security requirements. It complies with the stringent standards of the German Federal Office for Information Security (BSI) according to AIS 20/31 and is classified at EAL 3 (Evaluation Assurance Levels) as well as PTG 3 (Physical True Random Number Generator), providing important evidence of the system’s security.
