摘　　要：传统的卫星导航定位系统技术,其定位精度由于受限于电磁波脉冲的能量与带宽存在着一定的极限。随着量子力学的发展,利用具有量子纠缠特性的激光脉冲来取代电磁脉冲信号,可以实现趋近于物理极限的高定位精度,这就是量子定位技术。概述了量子定位的基本原理和特点优势的基础上,浅析了其关键技术及未来广阔应用前景。For the traditional satellite navigation and global positioning system, the positioning accuracy is limited by the energy and bandwidth of electromagnetic pulses. With the development of quantum mechanics, laser pulses are used to replace the electromagnetic pulse signal and realize a high positioning precision approximating the physical limits because of their quantum entanglement properties, which is named as“quantum positioning system”. To describe the basic principle and characteristics of the quantum positioning advantages, while its key technologies and the broad application prospect in the future are analyzed as well.
