J. P. Torres, A. Alexandrescu, L. Torner

摘要:

提出了自发参量下转换中双光子纠缠态空间模函数的量子螺旋带宽的概念。利用双光子态的轨道角动量本征态得到了带宽,并揭示了带宽与下转换晶体长度和泵浦光束腰的关系。讨论了量子螺旋带宽与量子态纠缠熵之间的关系。

英文摘要:

We put forward the concept of quantum spiral bandwidth of the spatial mode function of the two-photon entangled state in spontaneous parametric downconversion. We obtain the bandwidth using the eigenstates of the orbital angular momentum of the biphoton states, and reveal its dependence with the length of the down converting crystal and waist of the pump beam. The connection between the quantum spiral bandwidth and the entropy of entanglement of the quantum state is discussed.
