Quantum Wireless Imaging and Remote Sensing - State-of-the-Art Technologies and Opportunities

Quantum entanglement that does not exist in classic world suggests disruptive quantum i$m$age/sig$n$al processing and wireless sensing techniques beyond the frontier of classic image/signal processing and sensing. By showing the fundamental difference between classic and quantum techniques, this paper comprehensively explains the principles and mechanisms of quantum wireless ghost imaging, quantum radar, and secure quantum remote sensing, with suggestions toward future technological opportunities in communication and signal processing.
