Orbital angular momentum is a quantum state of the photon. The beam with orbital angular momentum has a wide application in optical communication and other fields and has become a hot spot of research at home and abroad. Orbital angular momentum became an important option of physics of quantum information carriers in free space, which will bring important influence in quantum communication field. This paper introduces what orbital angular momentum is and how to produce it. Two kinds of classical quantum cryptography communication solution based on phase and polarization coding are listed briefly in order to compare them with the proposed communication solution, which is the photon orbital angular momentum cryptography communication scheme. We put forward to it for example, and mainly represent its application and prospect.
