Abstract

A practical scheme for the demonstration of perfect one-sided device-independent quantum secret sharing is proposed. The scheme involves a three-mode optomechanical system in which a pair of independent cavity modes is driven by short laser pulses and interact with a movable mirror. We demonstrate that by tuning the laser frequency to the blue (anti-Stokes) sideband of the average frequency of the cavity modes, the modes become mutually coherent and then may collectively steer the mirror mode to a perfect Einstein-Podolsky-Rosen state. The scheme is shown to be experimentally feasible, it is robust against the frequency difference between the modes, mechanical thermal noise and damping, and coupling strengths of the cavity modes to the mirror.

摘要

提出了一种用于演示完美单边设备无关量子秘密共享的实用方案。该方案涉及一个三模光机械系统，其中一对独立的腔模由短激光脉冲驱动并与一个可移动镜相互作用。我们证明，通过将激光频率调谐到腔模平均频率的蓝（反斯托克斯）边带，这些模式变得相互相干，然后可以共同将镜模式引导到完美的爱因斯坦 - 波多尔斯基 - 罗森态。该方案被证明在实验上是可行的，它对模式之间的频率差、机械热噪声和阻尼以及腔模与镜的耦合强度具有鲁棒性。
