Secure and Robust Transmission and Verification of Unknown Quantum States in Minkowski Space

Executive Summary

An important class of cryptographic applications of relativistic quantum information work as follows. B generates a random qudit and supplies it to A at point P. A is supposed to transmit it at near light speed c to one of a number of possible pair wise space like separated points Q1 to Qn. A's transmission is supposed to be secure, in the sense that B cannot tell in advance which Qj will be chosen. This poses significant practical challenges, since secure reliable long-range transmission of quantum data at speeds near to c is presently not easy. Here the authors propose different techniques to overcome these difficulties.
