摘要

在量子信息和通信的情况下,在量子成像领域,纠缠是一种宝贵的资源。参量下转换(PDC)和四波混频等过程提供了具有空间纠缠特性的量子纠缠光束的自然来源,这在量子成像中很有用。我们将在PDC的情况下回顾这些众所周知的特征,以及允许成像灵敏度超过标准量子极限的技术,这已经在理论上预测[1]和实验证明[2]。

Natural and man-made in quantum imaging
As in the case of quantum information and communication, in the field of quantum imaging entanglement represents an invaluable resource. Processes such as parametric down-conversion (PDC) and four-wave mixing provide natural sources of quantum entangled beams endowed with spatial entanglement properties that are useful in quantum imaging. We will review these well known features in the case of PDC, and the technique which allows for an imaging with a sensitivity beyond the standard quantum limit, which has been theoretically predicted [1] and experimentally demonstrated [2].
