Quantum positioning and ranging via a distributed sensor network
نویسندگان
چکیده
A quantum sensor network with multipartite entanglement offers a sensitivity advantage in optical phase estimation over the classical scheme. To tackle richer sensing problems, we construct distributed four nodes via partite entanglements, unveil of higher order derivative radio-frequency signal phase, and unlock potential target ranging space positioning. Taking phased-array radar as an example, demonstrate optimal advantages for positioning missions. Without doubt, demonstration that endows innovative physical conception opens up widespread application networks.
