英文摘要：

We show firstly some advantages of the photonic crystal fiber in quantum information by reviewing several special characterizations in comparison with conventional silica fibers, then more focus on its application in quantum information. Being compared to traditional methods, like the spontaneously parametric down-conversion in a nonlinear crystal, the photonic crystal fibers can be used to generate entan-gled photons more efficiently. Besides, the entanglement source based on photonic crystal fiber is compatible with current optical fibers communication system, resulting in superiority and potentiality on quantum information. At last, we summarize photonic crystal fibers＇ promising developments.
