Quantum key distribution with trusted quantum relay
Helle Bechmann-Pasquinucci, Andrea Pasquinucci · arXiv (Cornell University) · 2005
A trusted quantum relay is introduced to enable quantum key distribution links to form the basic legs in a quantum key distribution network. The idea is based on the well-known intercept/resend eavesdropping. The same scheme can be used to make quantum key distribution between several parties. No entanglement is required.
