In this letter, we propose to implement quantum key distribution (QKD) by using a multi-band strategy. We present thorough noise analysis of quantum-classical coexistence while incorporating all relevant and precise parameters. Our research demonstrates that utilizing the entire extended C-band for transmitting classical channels (CChs) over L-band with bandwidth 75 GHz power 0 dBm yields no communication beyond 13 km. To address problem, utilize C+L-band serve CChs other bands (e.g., O, E,...
Quantum key distribution (QKD) revolutionizes secure communication, offering unbreakable cryptography against quantum computers' rising computational power. This paper explores the placement of trusted nodes to enhance efficiency communication networks. Two practical scenarios are investigated: multi-band (MB) setting, utilizing different wavelength bands for QKD and classical systems, multifiber (MF) solution, employing separate fibers communication. The study optimizes secret rate (SKR)...
Quantum key distribution over optical networks has been noted as a state-of-the-art approach to next-generation secure communication. We propose two approaches manage the signal for quantum exchange between trusted nodes; in first approach, channel (QCh) uses distinct fiber whereas classic (CCh) and public interaction (PICh) use another be transmitted on C-band (C+L band), second CCh PICh are C+L band QCh only O-band, both routed same fiber. In this context, variations of initial have put...
