Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-9 (2022)
A route to scalability for superconducting quantum computation is the modular approach, which however requires coherent microwave-to-optical conversion. Here the authors use gallium phosphide optomechanical crystal cavities for this task, exploiting
