Trans-Media Continuous-Variable Quantum Key Distribution via Untrusted Entanglement Source
IEEE Photonics Journal, 2021 We propose a continuous-variable quantum key distribution (CVQKD) scheme based on the atmosphere-to-seawater channel. In particular, an untrusted entanglement source (two modes of the compressed vacuum state, TMSV) is deployed on the surface of the ...
