【摘要】：二十一世纪是量子信息科学由理论走向应用的新时代，因此量子信息科学在近些年来成为最热门的学科之一。量子信息存储作为量子信息科学中不可或缺的部分，它既是组建量子通讯网络的基础，又是连接量子通讯和量子计算的关键，，使其变得尤为重要。近年来，量子存储方案被多次提出，目前提出的方案主要分布在固态、气态两种介质中。相对气态存储而言，固态存储方案具有高效率和高保真度的优点，而且走向实用化的潜力巨大。因此，基于可控逆转非均匀展宽（CRIB）的量子信息固态存储的意义就显而易见了。然而，这方面的研究工作大多还只是基于理想模型，作为量子中继器的基本因素，真正实现量子存储一直是研究的目标。由于时间比特存储具有很高的存储效率及保真度，因此，研究时间比特及其相关量的意义就显得与众不同。本文主要研究了以下几方面的内容：（1）建立具体的物理模型，计算和分析基于CRIB的量子固态存储方案的物理过程。（2）基于CRIB技术存储时间比特及纠缠对，并分析和计算整个物理过程及其性质和应用。(3)初步研究基于CRIB技术多模时间比特的存储。
[Abstract]:21th century is a new era of quantum information science from theory to application, so quantum information science has become one of the most popular subjects in recent years. Quantum information storage is an indispensable part of quantum information science. It is not only the foundation of constructing quantum communication network, but also the key to connect quantum communication with quantum computing. In recent years, quantum storage schemes have been proposed many times. The proposed schemes are mainly distributed in solid and gaseous media. Compared with gaseous storage, solid-state storage schemes have the advantages of high efficiency and high fidelity. Therefore, the significance of solid-state storage of quantum information based on controllable reverse non-uniform broadening (CRIBS) is obvious. However, most of the research work is based on the ideal model. As the basic factor of quantum repeater, the real realization of quantum storage is always the goal of research. Because of the high storage efficiency and fidelity of time bit storage, therefore, The significance of studying time bits and their related quantities is different. In this paper, we mainly study the following aspects: 1) establishing specific physical models. The physical process of quantum solid-state storage scheme based on CRIB is calculated and analyzed.; based on CRIB technology, time bits and entangled pairs are stored. The properties and applications of the whole physical process are analyzed and calculated. (3) the storage of multimode time bits based on CRIB technology is studied preliminarily.
