Abstract

We conduct an experimental study of continuous-variable quantum key distribution using a passive-state preparation scheme. Using an off-the-shelf amplified spontaneous emission source, we show that a secure key can be generated over metro-area distances.

We propose a passive continuous-variable quantum key distribution scheme, where Alice splits the output of a thermal source into two spatial modes, measures one locally and transmits the other mode to Bob after applying attenuation.
