Fujitsu develops diamond-spin quantum computer prototype
Fujitsu has announced the development of a prototype diamond-spin quantum computer that utilizes tin-vacancy (SnV) centers within diamond crystals. This approach, developed through joint research with Delft University of Technology and QuTech, aims to overcome limitations of current superconducting methods by offering higher stability and scalability through a modular architecture.
The prototype demonstrates approximately 10 times higher brightness than conventional nitrogen-vacancy (NV) center methods and operates at -271.6°C, a temperature higher than the typical operating range for superconducting quantum computers. Fujitsu has also successfully integrated these centers into photonic integrated circuits and demonstrated control via its Hybrid Quantum Computing Platform.
Fujitsu's long-term roadmap includes developing a multi-module diamond-spin prototype by 2027. The company aims to achieve practical quantum computing with 250 logical qubits by fiscal 2030 and 1,000 logical qubits by fiscal 2035. Future research will also focus on integrating diamond-spin technology with superconducting approaches to enable large-scale, error-tolerant quantum computing.
