| 摘 要： | 多光子纠缠态是量子通讯网络中的重要资源,光与二阶非线性介质相互作用的自发参变下转换过程是目前制备多光子态较成熟的方案之一.尽管脉冲光可以提高非线性转换效率并简化通信协议,但是进一步增强光与介质间的相互作用对提高多光子的产生效率依然必要.设计了飞秒脉冲激光谐振腔系统,在不改变脉冲重复频率和频率梳结构的情况下,提高了下转换...

| Abstract: | Multi-photon entangled states which are produced mainly by the process of spontaneous parametric down conversion between laser and second-order nonlinear material is a key resource in the quantum network.Although the application of pulsed laser improves the nonlinear conversion efficiency and simplifies the quantum communication protocol,it is still necessary to enhance the interaction between laser and material for improvement of multi-photon production rate.A resonant cavity for femtosecond pulse is desig... |
