Abstract:  Relativistic quantum information (RQI) was born in the wake of Quantum 2.0 revolution. It applies quantum
information to the problems of relativistic and gravitational physics (both as a technological tool and conceptual framework) and studies relativistic effects on quantum information carriers [1]. Similarly to its more conventional counterpart RQI combines quantum foundations and technology, and by bringing in additional physical considerations it identifies new bounds on quantum information processing as well as provides new possibilities for quantum protocols . To achieve its global reach Quantum 2.0 technology is getting deployed into space. I illustrate the opportunities and challenges of RQI by considering two examples of the gravitational effects: interferometry and spin-gravity coupling.
