SMF Coupled Compact Ground Terminal with Advanced Filtering Towards Daylight C Band Satellite QKD
Argiris Ntanos, Aristeidis Stathis, Panagiotis Kourelias +14
We demonstrate a compact, high-isolation C-band optical ground terminal for satellite QKD, achieving more than 120 dB daylight background suppression and 135 dB crosstalk noise iso…

Afterpulsing Effect on the Baseline System Error Rate and on the Decoy-State Quantum Key Distribution Protocols
Christos Papapanos, Dimitris Zavitsanos, Giannis Giannoulis +3
There is considerable interest in predicting the efficiency of Quantum Key Distribution (QKD) protocols when one of their implementation quantities is modified. One significant imp…

Studies on the readability and on the detection rate in a Mach-Zehnder interferometer-based implementation for high-rate, long-distance QKD protocols
Christos Papapanos, Dimitris Zavitsanos, Adam Raptakis +3
We study the way that chromatic dispersion affects the visibility and the synchronization on Quantum Key Distribution (QKD) protocols in a widely-used setup based on the use of two…
