Fujitsu has unveiled a diamond-spin quantum computer prototype utilizing tin-vacancy centers in photonic integrated circuits, operating at temperatures slightly warmer than superconducting systems. This milestone advances the modular architecture strategy essential for scaling quantum processors by combining high fidelity with efficient optical connectivity. The roadmap targets integration with superconducting approaches to achieve large-scale logical qubit systems by 2035.
Fujitsu Develops Diamond - Spin Quantum Computer Prototype

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 a test environment that it can be utilized via the Fujitsu Hybrid Quantum Computing Platform without any additional specialist knowledge. This development represents an important milestone toward realizing a modular architecture, one of the most promising approaches for scaling quantum computers, due to its high fidelity and efficient optical connectivity. The prototype is based…
