Robustness of entanglement-based discrete- and continuous-variable quantum key distribution against channel noise
Mikolaj Lasota, Olena Kovalenko, Vladyslav C. Usenko
Discrete-variable (DV) and continuous-variable (CV) schemes constitute the two major families of quantum key distribution (QKD) protocols. Unfortunately, since the setup elements r…
Cross talk compensation in multimode continuous-variable entanglement distribution
Olena Kovalenko, Vladyslav C. Usenko, Radim Filip
Two-mode squeezed states are scalable and robust entanglement resources for continuous-variable and hybrid quantum information protocols at a distance. We consider the effect of a…
Frequency multiplexed entanglement for continuous-variable quantum key distribution
Olena Kovalenko, Young-Sik Ra, Yin Cai +4
Quantum key distribution with continuous variables already uses advantageous high-speed single-mode homodyne detection with low electronic noise at room temperature. Together with…
Geometrical picture of photocounting measurements
O. P. Kovalenko, J. Sperling, W. Vogel +1
We revisit the representation of generalized quantum observables by establishing a geometric picture in terms of their positive operator-valued measures (POVMs). This leads to a cl…
