Tight finite-key analysis for two-parametric quantum key distribution
S. N. Molotkov · Laser Physics Letters · 2019
Abstract The analysis of a new two-parametric quantum cryptography protocol is presented. A fundamentally new feature of the protocol is that the detection of the eavesdropper occurs not only by the number of errors on the receiving side, but also by the number of photocounts in the control time slots. The second feature of this protocol is the fact that the protocol allows fiber implementation (Klimov et al 2018 Laser Phys. Lett . 15 075207), which does not use active optical elements (phase modulators and polarization controllers) on the receiving side.
