Fraunhofer Institute for Photonic Microsystems IPMS announces Q‑Dice, a high‑performance Quantum Random Number Generator (QRNG) that generates randomness based on quantum vacuum fluctuations. The system delivers true random numbers at bit rates exceeding 4 Gbit/s based on intrinsically random and uncontrollable quantum effects. 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.
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. By measuring inherently unpredictable quantum vacuum fluctuations, Q Dice developed by Fraunhofer IPMS 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.
“With Q-Dice, we make high-quality quantum randomness practically usable and accessible,” says Dr. Alexander Noack, Division Director Data Communication & Computing at Fraunhofer IPMS. “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.”
Fraunhofer IPMS QRNG Competencies
To ensure maximum reliability, Fraunhofer IPMS maintains all key competencies in house, enabling end to end development from photonics to system integration:
/• Laser and optical front end design for stable quantum noise generation and control
• Low noise analog front-end (AFE) enabling detection of quantum vacuum fluctuations
• High speed data acquisition (analog-to-digital conversion - ADC) and FPGA based randomness extraction/post processing
• System integration with high throughput interfaces, including 10 Gbit/s Ethernet connectivity
This end-to-end approach ensures precise control over signal quality, stability, and entropy extraction performance. The same physical noise source forms the basis for both hardware and cloud-based access to quantum entropy.
Two deployment models: hardware or cloud access
Fraunhofer IPMS offers Q-Dice in two configurations to support different operational requirements:
1. Q Dice Hardware Appliance (19-inch rack system):
An all in one hardware solution designed for on-premises deployment in data centers and on premises environments.
Q-Dice Key Specifications
• Random bit rate: 4.1 Gbit/s
• All in one solution
• 19-inch rack-mounted system (other form factors available on request)
• 10G Ethernet interface (additional interfaces on request)
• Designed for high-throughput integration environments and evaluated according to BSI AIS 20/31 and NIST SP 800-22 test suites.
2. Online QRNG on Demand (Entropy as a Service):
A secure online interface provides direct access to quantum-generated randomness without requiring dedicated hardware installation. The service enables rapid evaluation, prototyping, and scalable integration of quantum entropy into software systems and cloud-based applications.
As the technology moves into the implementation phase, Fraunhofer IPMS is looking toward collaborative growth. “We’re inviting partners to pilot the technology and co-create real-world applications,” Noack adds. “Our goal is to work together to raise the bar for security and trust in the digital age.”
