摘要:

纠缠增强的量子计量研究利用量子纠缠来提升测量精度。当探针中的粒子被制备为量子纠缠态时,它们会集体累积待测物理量的信息,从而使测量精度突破标准量子极限,逼近海森堡极限。量子操控与探测技术的快速发展,已使得在冷原子、囚禁离子等合成量子系统中实现多粒子纠缠态的产生、操控与探测成为可能。本文旨在回顾并阐明利用多粒子纠缠开展量子计量的基本原理与实验进展,并讨论纠缠增强型量子传感器的潜在应用。

英文摘要:

Entanglement-enhanced quantum metrology explores the utilization of quantum entanglement to enhance measurement precision. When particles in a probe are prepared into a quantum entangled state, they 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.
