Detectors, optical switches, and waveguides

A quantum computing method, comprising

• sustaining a vacuum below 10−3 millibar;
• tuning a plurality of optical resonators to a resonance of an alkali atom;
• maintaining the alkali atom within a mode of the optical resonators using at least one trapping laser;
• inducing photon emissions using an atom excitation laser;
• detecting a presence or absence of an atom-resonator coupling using a plurality of detectors;
• receiving output signals from the plurality of detectors;
• and
• controlling a plurality of optical switches to switch between a plurality of waveguides configured to couple photons to and from the optical resonators.

A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor, cause the at least one processor to carry out a quantum computing method, the method comprising:

• maintaining the alkali atom within a mode of the optical resonators using at least one trapping laser;
• inducing photon emissions using an atom excitation laser;
• detecting a presence or absence of an atom-resonator coupling using a plurality of detectors;
• receiving output signals from the plurality of detectors;
• and
• controlling a plurality of optical switches to switch between a plurality of waveguides configured to couple photons to and from the optical resonators.
