Extending the use of phased arrays (i.e. coherent arrays of antenna elements) to non-classical states of light would be useful for several quantum technologies, but losses and transceivers noise have hindered efforts so far. Here, the authors demonstrate a silicon photonic-electronic system able to perform 32-pixel imaging, beamforming and beamsteering of squeezed light transmitted over free space toward unlocking wireless applications of quantum technologies.
