Relativistic quantum sensing in near-Earth curved spacetime

报告摘要：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 channel-position finding 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 channel-position finding 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 channel-position finding and ranging protocols.
