Fraunhofer IPMS Launches Q-Dice: A Quantum Random Number Generator for Post-Quantum Security

Fraunhofer IPMS has introduced Q-Dice, a quantum random number generator designed to strengthen encryption, authentication, and future security infrastructure. The system generates randomness that hackers cannot predict or reverse, targeting cryptographic security challenges in a post-quantum computing world.

It looks like an old PC, but this bleeding-edge 'server' may well save us from hackers causing chaos in a post-quantum computing world - delivering 4.1 Gb/s of 'rackable' quantum random number generation that brings entropy to the data center.

Quantum Randomness Replaces Reliance on Conventional Algorithms

The system, known as Q-Dice, generates random numbers using quantum vacuum fluctuations rather than conventional software algorithms that may contain weaknesses. According to Fraunhofer IPMS, the technology delivers randomness at speeds exceeding 4 Gbit/s, with the hardware appliance rated at 4.1 Gbit/s.

Random number generation forms a fundamental component of encryption, authentication, secure communications, and access control systems throughout modern digital infrastructure. Weak or predictable randomness can undermine otherwise robust security mechanisms, creating opportunities for attackers to exploit cryptographic vulnerabilities.

Because Q-Dice randomness originates from quantum vacuum fluctuations rather than a mathematical formula, there is no underlying pattern for hackers to study. This means no seed value exists for attackers to calculate, predict, or reverse engineer, regardless of available computing power.

Fraunhofer IPMS says Q-Dice derives entropy from inherently unpredictable quantum effects, producing outputs suitable for applications including:

• Data encryption
• Authentication systems
• Secure communications
• Quantum key distribution
• Post-quantum cryptography

The organization claims that generated randomness was evaluated using recognized frameworks, including BSI AIS 20/31 and the NIST SP 800-22 test suite. The system also carries EAL 3 and PTG 3 classifications, reflecting compliance with security requirements established by Germany's Federal Office for Information Security.

Unlike many software-based approaches, the platform relies on physical quantum phenomena rather than mathematical procedures intended to simulate randomness.

Rack-Mounted Hardware and Cloud Access Offer Deployment Flexibility

Fraunhofer IPMS is offering the technology through both dedicated hardware and cloud-based delivery models to accommodate different operational requirements.

The primary hardware version arrives as a 19-inch rack-mounted appliance intended for deployment inside data centers and other controlled computing environments. The appliance combines quantum entropy generation, signal acquisition, randomness extraction, and system integration within a single platform featuring 10 Gbit/s Ethernet connectivity.

Fraunhofer IPMS said the development process remained entirely in-house, covering:

• Optical subsystem design
• Low-noise analog electronics
• High-speed data acquisition
• FPGA-based post-processing

For organizations unwilling to install dedicated equipment, the institute also provides an online Entropy-as-a-Service offering delivering quantum-generated randomness through a secure interface.

"With Q-Dice, we make high-quality quantum randomness practically usable and accessible," said Alexander Noack, Division Director Data Communication and 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 is now actively seeking partners to pilot the technology and help build practical, real-world applications around it. Noack added that the goal involves working collaboratively to raise the overall bar for security and trust as quantum computing capabilities continue advancing.

Whether Q-Dice becomes a standard component in next-gen security infrastructure, or remains a niche tool, depends on how quickly organizations recognize the urgency of post-quantum preparation.
