Fujitsu has unveiled a functional prototype of a diamond-spin quantum computer using tin-vacancy centers integrated into photonic circuits, marking a significant step toward scalable modular architectures. Operating at -271.6°C, this design potentially lowers cooling complexity compared to superconducting systems while enabling efficient optical connectivity for future multi-module scaling. The achievement highlights a distinct hardware pathway that could complement existing quantum approaches rather than replace them entirely.

Fujitsu builds a diamond-spin quantum computer prototype

Quantum ZeitgeistSeptember 8, 20262 min read

Fujitsu today announced the development of the world’s first working prototype of a diamond-spin quantum computer incorporating tin-vacancy (SnV) centers into photonic integrated circuits. The prototype, which can be operated at -271.6°C, has been demonstrated in a test environment via the Fujitsu Hybrid Quantum Computing Platform.

Fujitsu has developed the world’s first working prototype of a diamond-spin quantum computer incorporating tin-vacancy (SnV) centers into photonic integrated circuits. Operating at -271.6°C, this prototype surpasses the typical temperature of superconducting quantum computers by a fraction of a degree, potentially easing…
