论文摘要
自旋面积是一种良好的“量子技术”，在两级系统的集合中，精心设计的相关性降低了光谱实验的统计不确定性。本文回顾了该领域的一些重要进步，重点是作者关于反谐压施加的基本限制的贡献。在第一部分中介绍的材料的基础上，在上一部分中概述了新的想法和一些有希望的发展。
Spin-squeezing is a well-established "quantum technology", where well-designed correlations in an ensemble of two-level systems reduce the statistical uncertainty of spectroscopic experiments. This paper reviews some important advances in the field, with emphasis on the author's contributions concerning in particular the fundamental limits imposed by decoherence. Building on the material presented in the first part, new ideas and some promising developments are outlined in the last section.
