Nanofiber-Mediated Interaction of Light with Cold Atoms

Abstract

Light-matter interaction processes are extremely attractive for quantum information problems, where one of the main goals consists in a quantum state of light mapping into a collective atomic state. By analogy with the Purcell effect, which exhibits in the presence of a resonator, enhancement of light-matter interaction can be achieved by using a nanofiber [1-2]. In this work we present a theoretical description of light interaction with a cold atomic ensemble mediated the nanofiber, which lies in a base of the experimental realization of a quantum memory protocol [3].
