Quantum cryptographic ranging
Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone
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.
