Abstract

This paper investigates improvements to Quantum Key Distribution (QKD) protocols by leveraging the principles of quantum decoherence. The core claim centers on optimizing the decoherence process to enhance the security and key generation rate of QKD systems. This is achieved through a detailed analysis of the underlying physical mechanisms governing decoherence and the subsequent design of a novel decoherence suppression technique aimed at minimizing the decoherence time of quantum states. The proposed approach addresses a critical limitation in existing QKD protocols – the vulnerability to decoherence – while simultaneously boosting key generation efficiency. The theoretical framework presented demonstrates a significant potential for increased security and higher key rates, offering a pathway towards more robust and practical quantum cryptography. Mathematical models are presented to illustrate the key concepts and demonstrate the feasibility of the proposed method. The investigation focuses on the theoretical aspects of the protocol improvement, without experimental validation.
