摘要

纠缠增强量子计量学探索利用量子纠缠提高测量精度。当探针中的粒子被制备成合适的量子纠缠态时，它们可能会共同积累待测物理量的信息，从而提高测量精度，超越标准量子极限，接近海森堡极限。量子操纵和探测技术的飞速发展，使得在冷原子和被困离子等合成量子系统中生成、操纵和探测多粒子纠缠态成为可能。本文旨在回顾和说明量子计量学多粒子纠缠的基本原理和实验进展，并讨论纠缠增强量子传感器的潜在应用。

Entanglement-enhanced quantum metrology: From standard quantum limit to Heisenberg limit

Entanglement-enhanced quantum metrology explores the utilization of quantum entanglement to enhance measurement precision. When particles in a probe are prepared into a suitable quantum entangled state, they may collectively accumulate information about the physical quantity to be measured, leading to an improvement in measurement precision beyond the standard quantum limit and approaching the Heisenberg limit. The rapid advancement of techniques for quantum manipulation and detection has enabled the generation, manipulation, and detection of multi-particle entangled states in synthetic quantum systems such as cold atoms and trapped ions. This article aims to review and illustrate the fundamental principles and experimental progresses that demonstrate multi-particle entanglement for quantum metrology, as well as discuss the potential applications of entanglement-enhanced quantum sensors.

期刊介绍： Applied Physics Reviews (APR) is a journal featuring articles on critical topics in experimental or theoretical research in applied physics and applications of physics to other scientific and engineering branches. The publication includes two main types of articles: Original Research: These articles report on high-quality, novel research studies that are of significant interest to the applied physics community. Reviews: Review articles in APR can either be authoritative and comprehensive assessments of established areas of applied physics or short, timely reviews of recent advances in established fields or emerging areas of applied physics.
