Tightening the eavesdropping accessible information for continuous variable quantum key distribution protocols that involve nonmaximally entanglement

In this paper, we derive tight bounds for the eavesdropping attacks on continuous variable quantum key distribution (CV-QKD) protocol that involves nonmaximally entangled states. We show that deriving bounds on the eavesdropper’s accessible information based on the Heisenberg uncertainty yields upp...
