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 communications. In this paper, to overcome range limitations, we investigate a multi-hop underwater quantum key distribution (QKD) where intermediate nodes help the key distribution between the source and destination nodes. We consider deployment of passive-relays which …
