Q-Dice spits out true random numbers at a 4.1 Gigabits per second (Gbit/s).
In the digital world, there is no such thing as a perfect roll of the dice. Standard computers rely on predictable math formulas and deterministic code. It’s a structured approach that a clever hacker or a future quantum computer can easily reverse-engineer.
To fix this, the Fraunhofer Institute for Photonic Microsystems (IPMS) in Germany has unveiled Q-Dice. It is a fast, next-generation Quantum Random Number Generator (QRNG). It produces true random numbers by measuring inherently unpredictable quantum vacuum fluctuations, making it immune to algorithmic vulnerabilities.
But what makes this a massive milestone for cybersecurity is the raw speed. Q-Dice spits out true random numbers at a 4.1 Gigabits per second (Gbit/s).
“With Q-Dice, we make high-quality quantum randomness practically usable and accessible,” said 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,” Noack added.
Validated quality
Modern cybersecurity lives or dies by true randomness. When random number generators are weak or predictable, it opens the door for hackers to smash through encryption and authentication systems.
To secure modern cryptographic systems against the vulnerabilities of predictable data, Fraunhofer IPMS developed Q-Dic that harvests true randomness from unpredictable quantum vacuum fluctuations.
The system provides secure quantum entropy for next-generation encryption (such as QKD and PQC), secure communication, and large-scale simulations.
Fraunhofer IPMS has filled the gap between experimental physics and commercial IT infrastructure by offering Q-Dice in two deployment models: a 19-inch rack-mounted Hardware Appliance equipped with a 10G Ethernet port for on-premises data centers. And a cloud-hosted Entropy-as-a-Service (EaaS) platform that allows developers to stream true quantum randomness instantly via an API for rapid prototyping and scalable software integration.
Security compliance is also baked deeply into it. The system has already cleared rigorous testing from the German Federal Office for Information Security (BSI AIS 20/31) and the global NIST SP 800-22 suites. It holds an official PTG.3 physical true random designation, proving that the device cannot be manipulated or forecast by outside actors.
In-house competencies
It eliminates reliance on vulnerable mathematical algorithms and enables high data rates for security-critical applications such as post-quantum cryptography and secure communication.
Fraunhofer IPMS maintains the entire construction pipeline in-house, custom-building everything from the lasers to the analog sensors of vacuum fluctuations.
Furthermore, the institute handles its own high-speed ADC data acquisition, FPGA-based randomness extraction, and full-system integration with high-throughput 10 Gbit/s Ethernet connectivity, ensuring absolute control over signal quality and cryptographic security.
As cybersecurity braces for a post-quantum world where standard encryption keys will become obsolete, Q-Dice offers a concrete line of defense.
“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,” it stated.
The institute is currently moving into its pilot phase and is actively onboarding corporate partners to integrate this cosmic chaos into day-to-day enterprise tech.
