Title Complementarity and Propagation of Decoherence in relativistic quantum measurements
Abstract Under recent developments in quantum technologies, various possibilities of probing quantum nature of gravity have been discussed. One such proposal is given by Bose to detect quantum entanglement generation of two macroscopic objects through gravitational interactions, which reflects superposed states of different spacetimes. In my talk, I will explain how to calculate the entanglement generation and possible decoherence in the process of measurements based on closed-time path formalism of relativistic quantum field theories.
