PsiQuantum

PsiQuantum announced an optical circuit switch built on an advanced low-loss silicon photonics platform. The technology is aimed at routing data optically rather than electronically, a capability relevant to scaling large computing systems, including the quantum machines the company is developing. Details on performance and availability were not provided in the announcement, but the claim of a low-loss silicon photonics platform has drawn attention in technical communities discussing data center networking and photonic interconnects.
