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 on the results of joint research started in 2020 by Fujitsu, Delft University of Technology, and QuTech, a world-leading quantum technology research institute and part of TU Delft. Comment from Vivek Mahajan, Corporate Executive Officer, Corporate Vice President, CTO, in charge of System Platform, Fujitsu Limited \"The diamond-spin approach we have applied in this prototype not only offers exceptional scalability in its own...",
