摘要

对光子晶体光纤中产生的超宽带双光子态进行了基于施密特模式分析的量子纠缠度的数值估计。我们证明了这些状态具有高度的量子纠缠，即使当源被飞秒激光脉冲抽运宽带。

Analysis of Schmidt Modes of Ultra-Broadband Biphotons Generated in a Photonic Crystal Fiber

We presented numerical estimates of the degree of quantum entanglement based on Schmidt mode analysis for ultra-broadband biphotonic states generated in a photonic crystal fiber. We show that these states have a high degree of quantum entanglement even when the source is pumped broadband by femtosecond laser pulses.
