论文摘要
在非分类挤压器中产生的量子光具有许多应用，例如子弹射传输测量值，以最大程度地提高一个光子或量子照明提取的信息，以增加目标检测的概率。但是，到目前为止，任何应用都无法考虑这些实验中经常使用的一半的两部分下转换光子状态的热特性。我们在这里表明，通常被视为滋扰的最大混合状态确实可以用来提取有关物体位置的信息，同时提供有效伪装在其他热或背景光下。
Quantum light generated in non-degenerate squeezers has many applications such as sub-shot-noise transmission measurements to maximise the information extracted by one photon or quantum illumination to increase the probability in target detection. However, any application thus far fails to consider the thermal characteristics of one half of the bipartite down-converted photon state often used in these experiments. We show here that a maximally mixed state, normally viewed as nuisance, can indeed be used to extract information about the position of an object while at the same time providing efficient camouflaging against other thermal or background light.
