The team achieved coherent cooperativity above unity — a key threshold for high-fidelity quantum operations — and showed that a single quantum emitter can nearly completely control light transmission through the cavity. They also fabricated and tested 327 high-quality nanophotonic cavities across two chips, validating a scalable manufacturing approach. The work, published in PRX, is relevant to both quantum networking and modular quantum computing, including a collaboration with Fujitsu. ## Full article daily.dev links to this article rather than hosting it.
