Fujitsu's new diamond-spin quantum computer prototype marks a significant engineering milestone by integrating tin-vacancy centers into photonic circuits, offering a distinct thermal advantage over standard superconducting systems. The ability to operate at -271.6°C and the roadmap for modular scaling by 2027 suggest this platform could address critical bottlenecks in qubit connectivity and system integration. This development strengthens the competitive landscape for non-superconducting quantum architectures as the industry seeks viable paths toward large-scale practical computing.
Fujitsu Develops Diamond-Spin Quantum Computer Prototype

Insider Brief PRESS RELEASE — Fujitsu today announced that it has developed the world’s first working prototype of a diamond-spin quantum computer incorporating tin-vacancy (SnV) centers into photonic integrated circuits [1] [2]. The prototype can be operated at -271.6°C, higher than the typical operating temperature of superconducting quantum computers (-273.13°C) and Fujitsu has demonstrated in […]
Fujitsu developed what it describes as the world’s first working diamond-spin quantum computer prototype integrating tin-vacancy centers with photonic circuits. The prototype operates at minus 271.6 degrees Celsius and can be accessed through Fujitsu’s Hybrid Quantum Computing Platform. Fujitsu plans to develop a multi-module prototype by 2027 and is exploring integration with superconducting quantum computers. Image: The diamond-spin quantum computer prototype.
