使用热光直接测试“量子吸血鬼”阴影的存在
The direct test of the absence of the "quantum vampire's" shadow with use of thermal light
摘要：
量子物理学的反直觉性质导致了许多悖论。其中之一是“量子吸血鬼”效应[1]，即大光束的一部分中的光子湮灭不会改变光束轮廓的形状（即。例如，不投射阴影），但可能会改变总光束强度。以前，这种效应仅在简化的双模状态下得到证明[1，2]。本文利用光在输入端的热态直接检验光子湮灭后的阴影消失。
英文摘要：
Counterintuitive nature of quantum physics leads to a number of paradoxes. One of them is a "quantum vampire" effect [1] consisting in the fact, that photon annihilation in a part of a large beam doesn't change the shape of the beam profile (i. e., doesn't cast a shadow), but may change the total beam intensity. Previously this effect was demonstrated just in a simplified double-mode regime [1,2]. In the current paper the direct test of shadow absence after the photon annihilation has been performed with use of thermal state of light at the input.
