Abstract
A quantum computing system, method and computer readable medium involve a vacuum enclosure for sustaining a vacuum below 10−3 millibar, optical resonators tuned to a resonance of an alkali atom, and a trapping laser for maintaining the alkali atom within a mode of the optical resonators. An atom excitation laser induces photon emissions, a plurality of waveguides couple photons to and from the optical resonators, and a plurality of detectors detect a presence or absence of an atom-resonator coupling. A processor receives output signals from the detectors and controls optical switches for switching between two or more of the plurality of waveguides.
