Optomechanical interfaces for hybrid quantum networks Chunhua Dong, Yingdan Wang and Hailin Wang http://nsr.oxfordjournals.org/content/2/4/510.full ABSTRACT Recent advances on optical control of mechanical motion in an optomechanical resonator have stimulated strong interests in exploring quantum behaviors of otherwise classical, macroscopic mechanical systems and especially in exploiting mechanical degrees of freedom for applications in quantum information processing. In an optomechanical resonator, an optically- active mechanical mode can couple to any of the optical resonances supported by the resonator via radiation pressure.This unique property leads to a remarkable phenomenon:mechanically-mediated conversion of optical fields between vastly different wavelengths. The resulting optomechanical interfaces can play a special role in a hybrid quantum network, enabling quantum communication between disparate quantum systems. In this review, we introduce the basic concepts of optomechanical interactions and discuss recent theoretical and experimental progresses in this field. A particular emphasis is on taking advantage of mechanical degrees of freedom, while avoiding detrimental effects of thermal mechanical motion. Keywords: cavity optomechanics, radiation pressure, quantum networks, quantum optics, quantum state transfer |
