Quantum cryptographic ranging

  title={Quantum cryptographic ranging},
  author={Vittorio Giovannetti and Seth Lloyd and Lorenzo Maccone}
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. The following touching problem will be… CONTINUE READING
