Squeezed- and coherent-state quantum key distribution over a deployed hybrid fibre-free-space channel
Quantum networks will combine optical fibre with free-space links, yet continuous-variable quantum key distribution (CV-QKD) has been developed predominantly for one medium or the other, while operation across concatenated fibre-free-space channels remains largely unexplored. The two media impose contrasting requiremen...
