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…
