We review a quantum key distribution protocol, recently proposed by us, that makes use of a two-way quantum channel. We provide a characterization of such a protocol from a practical perspective, and consider the most relevant individual-particle eavesdropping strategies against it. This allows us to compare its potentialities with those of the standard BB84 protocol which uses a one-way quantum channel.

Abstract
We review a quantum key distribution protocol, recently proposed by us, that makes use of a two-way quantum channel. We provide a characterization of such a protocol from a practical perspective, and consider the most relevant individual-particle eavesdropping strategies against it. This allows us to compare its potentialities with those of the standard BB84 protocol which uses a one-way quantum channel.File in questo prodotto:
