Opt. {\bf 4}, S415, (2002) Abstract We present a system to measure the distance between two parties that allows only trusted people to access the result. The security of the protocol is guaranteed by the complementarity principle in quantum mechanics. The protocol can be realized with available technology, at least as a proof of principle experiment.         Home | About the Program | Our Research | Publications | People Related MURIs | Contact © Massachusetts Institute of Technology
