Fraunhofer 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.” Further information on QRNG technologies and competencies at Fraunhofer IPMS is available at: Quantum Random Number Generation (QRNG) – Fraunhofer IPMS

With the investment, PostScriptum will become a shareholder in SemiQon, a Finnish quantum hardware company building one of Europe’s most ambitious platforms for next-generation quantum technology. The investment will help accelerate the commercialization of SemiQon’s breakthrough technology and support the company’s path toward becoming a leading European quantum hardware company. Finland’s position as a leader in commercial quantum technology receives a major boost from an investment in SemiQon by PostScriptum, the founder’s office led by Peter Sarlin. SemiQon is a world-leading supplier of cryo-optimized electronics for quantum computers. SemiQon has reached a stage where its technology is productized with components now deployed in working quantum systems. SemiQon’s customers include quantum computer manufacturers and system integrators. The silicon chip developed by SemiQon is optimized for operation near absolute zero and is a key component in scaling quantum computers from today’s hundreds of qubits to hundreds of thousands, or even millions, of qubits. This is the level at which quantum computers are expected to surpass classical computers and supercomputers. PostScriptum will provide SemiQon with a strong partner for scaling its commercial operations and accelerating growth. “Quantum computing will define the next era of compute, and the million-qubit era will be powered by developments in control electronics, cooling and other enabling technologies. SemiQon provides cryogenic-ready quantum hardware that enables scalable, affordable, and sustainable quantum computing. Backing SemiQon is one of the most significant bets PostScriptum has made, and we are committed to it for the long term”, says Peter Sarlin, founder and Chairman of PostScriptum. “Finland has become a leading hub for quantum technology research and commercialization in Europe and globally. When we first spoke with Peter, we immediately saw an opportunity to build a new success story around SemiQon’s technology”, says Antti Vasara, Chair of the Board of SemiQon. Ready for industrial scale SemiQon was established in 2023 to continue the commercialization of technology developed by VTT Technical Research Centre of Finland Ltd. After a three-year research phase, SemiQon entered the commercial phase earlier this spring. The silicon-based Cryo-CMOS technology developed by SemiQon is a key platform for moving quantum computers from experimental laboratory systems to commercial products. “This past spring has shown that there is significant interest in our product. Our customers’ trust is based on our ability to deliver top-quality components, and we are not tied to a single approach to building quantum computers. Our support for multiple quantum computing modalities is a significant advantage as we build critical enabling technologies for the future and strengthen Europe’s position in the global quantum industry,” says Himadri Majumdar, Co-Founder and CEO of SemiQon. The cryo-optimized CMOS platform is designed and manufactured in line with existing standards for silicon-based semiconductors. It can be produced at industrial scale using the same methods and equipment as today’s silicon microchips. The company designs and manufactures its products in Otaniemi, Espoo. “Our goal is to make SemiQon the world’s leading enabling technology provider in quantum. What Peter and the team bring, expertise, networks, vision, is exactly the capital that matters most at this stage.” Majumdar continues.   What is Cryo-CMOS? It addresses a major bottleneck in scaling quantum computers by bringing the quantum processors readout and control electronics closer to the processor itself. The electronics must operate at temperatures close to absolute zero without interfering with the qubits. By enabling control and readout inside the cryostat, the technology can significantly reduce the wiring infrastructure currently required between the quantum processor and room-temperature electronics. This is a prerequisite for scaling quantum computers into commercially viable systems. Cryo-CMOS is compatible with existing semiconductor design and manufacturing standards and can be produced using established silicon chip manufacturing methods. Beyond quantum computing, the applications of SemiQon’s Cryo-CMOS technology extend to other critical industries such as space technologies and high-performance computing. ‍ About SemiQon SemiQon’s mission is to realize the promise of quantum computing by delivering scalability through powerful, resilient, and cost-effective silicon-based quantum hardware. Its technology builds upon decades of development and know-how from the semiconductor industry, making its cryo-optimized CMOS electronics commercially competitive and well-suited for mass-manufacturing. SemiQon’s first-in-the-world cryo-optimized CMOS delivers scalability and power efficiency to wide-ranging applications in quantum, space, and beyond.
