双光子成像随机延迟选择量子擦除器

Random Delayed-Choice Quantum Eraser via Two-Photon Imaging

Giuliano Scarcelli, Yu Zhou, Yanhua Shih

摘要:

我们报道了一个基于纠缠光子对的双光子成像方案的延迟选择量子擦除实验。在探测到通过双缝的光子后,通过测量其远距离纠缠孪生子,随机延迟选择擦除或不擦除哪条路径信息,然后由一组联合探测装置分别同时记录光子的类粒子和类波动行为。本发明的擦除器利用双光子成像。光子的完整路径信息通过“鬼像”传递到它的遥远的纠缠孪生子。在读取双光路的“完全信息”或“部分信息”之间,在鬼像的傅立叶变换平面上进行选择。

英文摘要:

We report on a delayed-choice quantum eraser experiment based on a two-photon imaging scheme using entangled photon pairs. After the detection of a photon which passed through a double-slit, a random delayed choice is made to erase or not erase the which-path information by the measurement of its distant entangled twin; the particle-like and wave-like behavior of the photon are then recorded simultaneously and respectively by only one set of joint detection devices. The present eraser takes advantage of two-photon imaging. The complete which-path information of a photon is transferred to its distant entangled twin through a "ghost" image. The choice is made on the Fourier transform plane of the ghost image between reading "complete information" or "partial information" of the double-path.
