Abstract
Microwave is widely used in present navigation system. It works well, yet it faces precision limit and other challenges. Quantum entanglement has been applied in various fields and resulted in quite remarkable improvements, especially in precision performance. Hence, we attempt to apply quantum entanglement to enhance merits of navigation system performed in microwave regime. This paper introduces principles of microwave-optical entanglement prepared by electro-opto-mechanical converters in detail. Meanwhile, a navigation ranging scheme exploiting this type of entanglement is proposed. The performance of the scheme is analyzed, and factors influencing entanglement feature and ranging feature are discussed. It shows that the ranging scheme has achieved quite precise results with help of microwave-optical entanglement, and it may be regarded as a promising candidate of new navigation ranging scheme.

Summary
Quantum entanglement is the core of quantum mechanics. As a significant quantum source, it has been widely applied and resulted in various frontier interdisciplines [1]–[3]. Cavity output of microwave and optical wave are entangled, and microwave photodetection is turned to optical wave photodetection, which is convenient and efficient. Another EOM converter application research involves microwave quantum illumination [14], which is proved to be more effective in sensing low-reflectivity objects theoretically. We propose a navigation ranging scheme based on quantum microwave-optical (M-O) entanglement, which is facilitated by EOM converter. We introduce the basic principles of quantum entanglement based on EOM converter and realization of our navigation ranging scheme in detail. The results show that our ranging scheme is remarkable and promising
