中文摘要: Quantum entanglement is the main resource to endow the field of quantum information processing with powers that exceed those of classical communication and computation. Due to low absorption and negligible nonbirefringent character in atmosphere, optical free space therefore serves as the most promising channel for large-scale quantum communication by use of satellites and ground stations. The acquisition, tracking and pointing (ATP) system is one of the most important parts of quantum experiment system, and it controls a transmitting and receiving laser beam within a few micro radians jitter because of using an extremely narrow beam divergence of several micro radians. This paper introduces the cascade ATP systems for 100km quantum entanglement distribution experiment among Charlie, Bob and Alice station. The specification and optical diagram of each ATP system are presented. The ATP system of Alice station is described in detail, it has coarse, fine and ultra-fine loop. In the 100km quantum entanglement distribution experiment, a tracking error of 4μrad is achieved for 70Hz bandwidth. The ATP strategy in this experiment can be used in the prospective satellite-to-ground quantum distribution. © 2013 Copyright SPIE.
