Scaling up quantum optics experiments requires on-chip reconfigurable quantum photonics, but their integration with detectors is a challenge. We show microelectromechanical reconfiguration of photonic circuits with on-chip superconducting single–photon detectors and demonstrate key applications.

Abstract The miniaturization of atomic quantum systems and their integration into silicon microchips paves the way for a wide variety of applications in quantum computing, metrology and magnetometry. A particular interest is found in the integration of quantum entities into the micro and nanoscale photonic resonators to implement chip scale cavity quantum electrodynamics. Here we demonstrate the interaction of a chip scale micro disc resonator with thermal rubidium atoms via the evanescent field of the mode. We observe high Rabi splitting of 4 GHz in the transmission spectrum of the coupled photonic-atomic system due to collective enhancement of the coupling rate by the ensemble of hot atoms and present a theoretical model to support the measured results. This result corresponds to atom-photon cooperativity of ~ 1. Such cooperativity is the onset for quantum interference, needed for high-end chip scale quantum technologies, such as such as quantum manipulation, quantum information storage and processing, and few photon switching.
