Abstract

This paper introduces a novel quantum key distribution (QKD) protocol, termed "Adaptive Quantum Key Distribution (AQKD)," that leverages quantum entanglement to establish secure communication channels. AQKD distinguishes itself through a dynamic mechanism that adjusts the security of the key distribution process based on the quantum system's state. This adaptive nature enhances key protection and efficiency by incorporating a feedback loop that responds to subtle changes in the entangled state. The core of the protocol involves utilizing entangled states for key generation and distribution, with a novel mechanism for dynamically adjusting the entanglement's strength based on observed quantum phenomena. We present a detailed mathematical framework and preliminary experimental validation demonstrating the protocol's effectiveness and robustness. The research explores the potential of AQKD to overcome limitations of existing QKD protocols, particularly in scenarios requiring resilience against noise and adversarial attacks. This work contributes to the advancement of secure communication technologies utilizing the unique properties of quantum mechanics.
