First experimental implementation of a two-way QKD protocol with decoy states over free space medium.
Findings
Increased maximum secure distance achieved.
Successful demonstration of two-way QKD with decoy states.
Potential for enhanced free space quantum communication.
Abstract
We report on the first demonstration of a two way Quantum Key Distribution protocol with decoy state. The experiment was conducted over free space medium and exhibits a significant increase in the maximum secure distance.
