- Abstract: Current technological progress is driving Quantum Key Distribution towards a
commercial and world widescale expansion. Its capability to deliver
unconditionally secure communication will be a fundamental feature in the next
generations of telecommunication networks. Nevertheless, demonstrations of QKD
implementation in a real operating scenario and their coexistence with the
classical telecom infrastructure are of fundamental importance for reliable
exploitation. Here we present a Quantum Key Distribution application
implemented overa classical fiber-based infrastructure. By exploiting just a
single fiber cable for both the quantum and the classical channel and by using
a simplified receiver scheme with just one single-photon detector, we
demonstrate the feasibility of low-cost and ready-to-use Quantum Key
Distribution systems compatible with standard classical infrastructure.
