Coherent cavity networks with complete connectivity

Abstract

When cavity photons couple to an optical fiber with a continuum of modes, they usually leak out within a finite amount of time. However, if the fiber is about 1 m long and linked to a mirror, photons bounce back and forth within the fiber on a much faster time scale. As a result, dynamical decoupling prevents the cavity photons from entering the fiber. In this paper, we use the simultaneous dynamical decoupling of a large number of distant cavities from the fiber modes of linear optics networks to mediate effective cavity–cavity interactions in a large variety of configurations. Coherent cavity networks with complete connectivity can be created with potential applications in quantum computing and in the simulation of the complex interaction Hamiltonians of biological systems.
