Fujitsu develops a diamond spin quantum computer prototype integrating tin-vacancy centers and a photonic integrated circuit

Fujitsu has developed the world’s first working prototype of a diamond spin quantum computer that integrates tin-vacancy (SnV) centers into a photonic integrated circuit. It can operate at -271.6°C, warmer than the typical operating temperature of superconducting quantum computers, -273.13°C. The prototype is based on joint research Fujitsu has conducted with Delft University of Technology and QuTech since 2020, and has been validated for use on its hybrid quantum computing platform.
