量子光学计量学--High-N00N态的揭秘

Quantum Optical Metrology -- The Lowdown on High-N00N States

Jonathan P. Dowling

摘要:

光的量子态,如压缩态或纠缠态,可以用来进行测量(计量学),产生图像,并以远远超过经典可能的精度感测物体,也超过了曾经被认为是可能的量子力学。其主要思想是利用量子效应克服计量学中的散粒噪声极限和成像和传感中的瑞利衍射极限。近年来,随着来自快速发展的光学量子信息处理领域的思想的涌入,量子光学计量学得到了推动。这两个研究领域都利用了光的量子纠缠态的创造和操纵。我们将回顾量子光学计量学这一令人兴奋的新领域的一些最新理论和实验进展,重点介绍利用特定双模纠缠光子态-High-N 00 N态的例子。

英文摘要:

Quantum states of light, such as squeezed states or entangled states, can be used to make measurements (metrology), produce images, and sense objects with a precision that far exceeds what is possible classically, and also exceeds what was once thought to be possible quantum mechanically. The primary idea is to exploit quantum effects to beat the shot-noise limit in metrology and the Rayleigh diffraction limit in imaging and sensing. Quantum optical metrology has received a boost in recent years with an influx of ideas from the rapidly evolving field of optical quantum information processing. Both areas of research exploit the creation and manipulation of quantum-entangled states of light. We will review some of the recent theoretical and experimental advances in this exciting new field of quantum optical metrology, focusing on examples that exploit a particular two-mode entangled photon state -- the High-N00N state.
