| 摘 要： | 介绍了一种特殊的计算全息图，它能把零阶高斯光束转变为高阶拉盖尔一高斯光束，而高阶拉盖尔．高斯（LG）模是光子轨道角动量（Orbita lAngular Momentum）的本征态，因此相同模式的光子具有确定的轨道角动量，利用轨道角动量编码，可以实现多维量子通信。

| Abstract: | We present a special kind of computer-generated holograms which can convert the fundamental zero-order Gaussian mode into the high-order Laguerre-Gaussian modes. Since these modes are eigenstates of the orbital angular momentum, the propagating photons of the same spatial modes have a definite value of OAM. Therefore, we can encode quantum information in multidimensional states with some definite value of OAM. |
