Abstract

This work proposes an encoding–decoding procedure, which is characterized with higher efficiency, i.e., it increases the size of the sifted key. The contribution comes from using a novel way of decoding the data carried by the quantum systems. The proposed approach is analyzed in terms of efficiency, security, randomness, error rate, and capability of high dimensionality. It is shown that the newly proposed technique demonstrates higher efficiency, slightly better security, similar randomness, compatibility with high dimensionality, but less error robustness than the standard encoding–decoding scheme.
