Abstract

In this review, we discuss some of the usages of dissipative dipolar systems in the context of quantum technology. Due to the presence of a thermal environment, long-time storage and processing of quantum information is challenging. We provide two examples, where the quantum coherence and entanglement can be preserved for a long time scale using the dissipative dipolar systems. In the third example, we discuss the effect of the rapid rotation in reducing the line broadening of NMR spectrum of such systems. Our main focus is on the second-order effect of dipolar coupling in all the cases mentioned above. There are several ways to calculate such second-order effects. Hence, we present a brief overview of the dynamics of a dissipative dipolar coupled system and also show that the recently proposed fluctuation-regulated quantum master equation (FRQME) is an efficient tool for the theoretical analysis of such systems.

耗散偶极系统在量子技术中的应用

摘要

在这篇综述中，我们讨论了耗散偶极系统在量子技术背景下的一些用法。由于热环境的存在，量子信息的长期存储和处理具有挑战性。我们提供了两个例子，其中使用耗散偶极系统可以长时间保持量子相干性和纠缠性。在第三个例子中，我们讨论了快速旋转对减少此类系统 NMR 谱线展宽的影响。我们主要关注上述所有情况下偶极耦合的二阶效应。有多种方法可以计算此类二阶效应。因此，我们对耗散偶极耦合系统的动力学进行了简要概述，并表明最近提出的涨落调节量子主方程（FRQME）是此类系统理论分析的有效工具。
