Fraunhofer Institute for Applied Solid State Physics IAF has officially brought online its diamond-based QB-QDK2.0 system from Quantum Brilliance, marking a go-live milestone for Europe’s first room-temperature quantum accelerator using nitrogen-vacancy (NV) centers. The installation follows the system’s initial purchase in late 2024 and represents a key advance in integrating quantum accelerators into high-performance computing environments.
The QB-QDK2.0 system is now fully operational within Fraunhofer IAF’s quantum computing infrastructure in Baden-Württemberg, Germany. Installed without cryogenic requirements, the device fits into a standard 19” rack and is co-located with classical processors and NVIDIA GPUs to support hybrid quantum-classical workloads. The system is integrated with the open-source Qristal SDK and Emulator, allowing users to explore quantum-classical algorithms across fields such as quantum machine learning.
According to Fraunhofer IAF Director Prof. Rüdiger Quay, the compact form factor of the QB system enables seamless deployment in existing server environments. The accelerator will be made accessible to industrial and academic partners following a test phase, forming part of a broader application lab that also includes a separate NV-based quantum system developed by the University of Stuttgart.
Quantum Brilliance’s technology relies on synthetic diamond qubits, offering long coherence times and resilience to environmental noise at room temperature. This latest deployment is supported by SVA System Vertrieb Alexander GmbH and aligns with the regional quantum roadmap under the QuantumBW initiative, which promotes NV-based platforms for real-world applications.
With the system now live, Fraunhofer IAF will provide researchers and developers access to test NV-based quantum computing technologies under operational conditions. Read the official announcement from Fraunhofer IAF here.
