Advances in space quantum communications - Sidhu - 2021 ...

A second, natural alternative approach to QKD protocols is to use continuous-variable (CV) systems [83-95]. In general, thanks to the use of an infinite-dimensional Hilbert space, CV systems can transfer more information per signal compared with qubit-based approaches and rely on cheaper technological implementations; this advantage can be ...
