Multi-hop quantum key distribution with passive relays over underwater turbulence channels
Multi-hop quantum key distribution with passive relays over underwater turbulence channels
Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communication links. In this paper, as a potential solution to overcome range limitations, we investigate a multi-hop underwater quantum key distribution (QKD) where intermediate nodes between the source and destination nodes help the key distribution. We …
