There are fundamental rules and principles setting the limits of physical systems. It triggers an interesting thought—can we break the limits under specific circumstances? A realistic system can only provide limited functionalities because its performance is physically constrained by some fundamental principles. ‘Breaking the limit’, which usually implies that the capability of a system could be enhanced significantly, is intriguing in many research areas such as high-precision metrology, imaging and nanophotonics.

什么限制限制？

有一些基本的规则和原则来设定物理系统的限制。它引发了一个有趣的想法——我们能否在特定情况下突破限制？一个现实的系统只能提供有限的功能，因为它的性能受到一些基本原则的物理限制。“突破极限”通常意味着可以显着增强系统的能力，在高精度计量学、成像和纳米光子学等许多研究领域引起了人们的兴趣。
