确定性量子分束器的实验研究
Experimental Investigation of Deterministic Quantum Beam Splitter of Femtosecond Pulse
摘要
基于“时间反演”的HOM干涉原理, 利用一个普通的分束器将Ⅰ类自发参量下转换过程产生的一对飞秒脉冲量级、简并单光子对完全分离, 分束效率最高可以达到92％。
Abstract
Based on the principle of “time-reserved” HOM interference, we demonstrate that the completely degenerate femtosecond photon pairs, which come from the type-I spontaneous parametric down conversion process, can be deterministically separated by an ordinary 50∶50beam splitter. The maximum splitting efficiency is 92％.
