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.

In summary, we conduct experimental studies on the recently proposed passive CV-QKD using a commercial off-the-shelf ASE source. We demonstrate that a secure key can be generated over metro-area distances. This work was performed at Oak Ridge National Laboratory, managed by UT-Battelle, LLC, under Contract No. DE-AC05-00OR22725 for the DOE. We acknowledge support from the DOE Office of Cybersecurity Energy Security and Emergency Response (CESER) through the Cybersecurity for Energy Delivery Systems (CEDS) program.
