In this paper we investigate the chromatic dispersion impact on the quantum key distribution
system based on multi-mode weak coherent phase-coded states. We provide an asymptotic …

Phase encoding in quantum key distribution (QKD) enables long-distance information-

We experimentally prove a novel two-dimensional QKD scheme, relying on differential
phasetime shifting (DPTS) of strongly attenuated weak coherent pulses. We demonstrate …

Quantum key distribution (QKD) provides an attractive solution for secure communication.
However, channel disturbance severely limits its application when a QKD system is …

Quantum key distribution (QKD) can offer communication with unconditional security and is
a promising technology to protect next generation communication systems. For QKD to see …

We investigate quantum key distribution (QKD) in optical multiple-input-multiple-output
(MIMO) settings. Such settings can prove useful in dealing with harsh channel conditions as …
