The work, published in Optica, details a new chip-based system that can control multiple quantum light sources simultaneously using a single optical bus. This innovation, based on a novel silicon photonics platform, paves the way for efficient, long-distance distribution of. High-precision quantum signal transmission system engineered for secure key generation, satellite communication, and next-generation quantum networks. In this work we describe how optomechanical transduction of phase information from coherent optical pulses to superconducting qubit states followed by the execution of trained short-depth variational quantum circuits can perform joint detection of communication codewords with error probabilities. A team of researchers from UC Berkeley's Department of Electrical Engineering and Computer Sciences (EECS) and Lawrence Berkeley National Laboratory's Materials Sciences Division has made a significant leap toward building compact and scalable quantum networks. The system uses a laser diode at room temperature to send both. NASA SCaN is a program for all of NASA's space communications activities, which enables both NASA and non-NASA missions.
