What is 自发参数下变频?

自发参数下变频is as an optical quantum process in which an incident photon is converted into pairs of entangled photons by a 没有 n-linear medium.

简介 自发参数下变频

自发参数下变频(SPDC) is also known as parametric scattering or parametric fluorescence. The state of the 没有 n-linear crystal remains the same after 数据中心 has occurred.

转换背后的基本原理是能量守恒定律。 数据中心是量子光学领域的重要现象。晶体的非线性导致成对的光子自发发射。本文将探讨自发参数下变频现象的实验设置,工作和应用。

实验装置

用于SPDC的设备包括一个高功率激光束,称为泵浦源。非线性介质由β硼酸钡晶体组成。非线性介质也表现出双折射。知识开发计划(磷酸二氢钾)晶体也可用作SPDC的非线性介质。

通过将强激光束对准双折射的非线性光学介质来完成自发的参数下转换。通过遵循能量守恒定律,入射光子被转换为一对光子,其轴相对于入射光束对称排列。

The pair of photons produced by the process of 数据中心 has energy and momentum levels that are equal to the energy of the original photon and match the phase of the original photon.

的应用 自发参数下变频

Some of the typical applications of 数据中心 include:

  • 光场创造
  • 量子密码学
  • 量子信息实验。
