內容簡介：Quantum sensing is a quantum technology that uses quantum systems, quantum properties or quantum phenomena to improve the measurement accuracy of physical quantities. Recently, quantum sensing has emerged as a unique and rapidly growing branch of research in the field of quantum science and technology. As one of the most important tasks of quantum sensing, quantum illumination is an entanglement assisted target detection scheme that uses an optimal quantum receiver and has a good advantage over the optimal classical strategy in terms of error exponent. In this talk, I will briefly introduce the recent progresses on the study of quantum enhanced illumination and quantum ranging in the near-Earth curved spacetime. Particularly, I will focus on how the gravitational effect of the Earth influences the performance of the quantum illumination and ranging protocol. Additionally, I will also introduce the effect of the gravity-induced quantum decoherence on the precision of quantum sensing tasks.
