通过Hong-Ou-Mandel干涉实现二阶叠加运算

Second-order superposition operations via Hong-Ou-Mandel interference

Su-Yong Lee, Hyunchul Nha

摘要:

我们提出了一个实验方案来实现二阶非局域叠加操作及其变种的方式Hong-Ou-Mandel干涉。二阶相干操作使我们能够以一种预示的方式产生高粒子数的NOON态,也可以用来增强连续变量态的纠缠特性。我们讨论了我们提出的方案的可行性,考虑现实的实验条件,如开关光电探测器与非理想的效率和不完善的单光子源。

英文摘要:

We propose an experimental scheme to implement a second-order nonlocal superposition operation and its variants by way of Hong-Ou-Mandel interference. The second-order coherent operations enable us to generate a NOON state with high particle number in a heralded fashion and also can be used to enhance the entanglement properties of continuous variable states. We discuss the feasibility of our proposed scheme considering realistic experimental conditions such as on-off photodetectors with nonideal efficiency and imperfect single-photon sources.
