Practical quantum key distribution gain is usually less than the theoretical limit, this is due to the imperfection of physical devices, quantum channels, and the lost qubits due to test carried out for for the identification of the presence of an eavesdropper and the consequence reduction of obtained knowledge. In this paper a technique is presented to(More)
Some quantum key distribution (QKD) technics — BB84, B92 [4], [5] for example — have a gain problem comparing the fnal key to the generated pulses of quantum particles. RUQB [1] technique improves the gain of BB84 by 5.5%, the improvement was achieved by fnding the relationship among the random bits that where initially generated, then(More)
