摘要/Abstract

摘要：

本文针对位移操作辅助下的量子线性放大器进行了研究.量子线性放大器可以提高量子态传输的保真度,提高量子通信抗干扰、抗损耗能力.本文针对目前量子线性放大器放大增益和放大成功概率低的问题,提出了相干位移增强型量子线性放大器,给出了位移操作提升量子线性放大器的机制,推导出放大增益得以进一步提高所需的位移操作的阈值,并结合态空间向光子数空间转化定理,在0-1光子数空间和多光子空间中同时验证了放大增益对位移量之间的依赖关系.

Abstract:

Quantum linear amplifier is an important tool to enhance already-known quantum communications.It can be used to protect the quantum state against photon loss.However,the gain and the probability of success in amplification is quite low.To this point,we propose to use coherent displacement operations to enhance quantum linear amplifiers.We derive the exact threshold beyond which local displacement helps to enhance distillation.We apply our state transfer theorem and numerically evaluate the dependence of quantum linear amplifiers gain on the amounts of displacement.

Key words: quantum optics, quantum displacement operations, quantum linear amplifier
