This research presents a novel quantum communication protocol that leverages classical error-correcting codes to enhance the robustness of superdense coding against photon loss and detector dark counts. By integrating entanglement distribution directly into the transmission process, the approach achieves superior data rates and energy efficiency for short-distance Quantum Local Area Networks (QLANs). The study provides rigorous theoretical bounds and a physical error model to guide the implementation of practical quantum links.
Classical Communication Protocol based on Joint Classical-Quantum Coding
arXiv:2609.16938v1 Announce Type: new Abstract: We introduce a robust quantum communication protocol that integrates classical error-control coding, entanglement distribution, and superdense coding. Classical error-correcting codes are used to mitigate dark counts and photon losses by determining the positions of qubit transmissions and protecting the data embedded through superdense coding. We derive conditions on the employed codes that guarantee successful error correction under a bounded error-frequency model. Moreover, upper bounds are derived on the performance of conventional superdense coding protected by classical error correction. It is shown that, under the same constraints on error frequency, suitable code configurations of the proposed protocol can exceed those upper bounds both in terms of data rate and energy efficiency. Finally, we develop a physical error model based on fiber attenuation, detector efficiency, dark counts, and time-slot duration, and use it to evaluate the effective performance of different configurations of error-correcting codes. The proposed approach is primarily suited for short-distance quantum links, as in Quantum Local Area Network (QLAN) where it can provide high communication throughput while integrating entanglement distribution directly into the communication process.
