Abstract

This paper proposes a novel approach to Quantum Key Distribution (QKD) termed Non-Deterministic Quantum Key Distribution (NQD-QKD). The core claim is that incorporating a mechanism of quantum non-determinism significantly enhances the security of QKD protocols and addresses the inherent "eavesdropper advantage" found in traditional QKD systems. NQD-QKD achieves this by leveraging the inherent randomness within quantum entanglement and employing a multi-faceted approach to key generation that moves beyond reliance on single-measurement probability analysis. Specifically, we introduce a process of multi-evaluation and filtering of quantum measurement results during key generation, coupled with robust noise modeling and control to enhance the resilience of the non-deterministic mechanism. The resulting system presents a more complex and unpredictable key generation process, dramatically increasing the difficulty for an eavesdropper to track information and compromise the key. The theoretical framework and mathematical description of NQD-QKD are presented, providing a foundation for future research and implementation.

Quantum Key Distribution Based on Quantum Decoherence

Jincheng Zhang

This paper investigates a novel approach to quantum key distribution (QKD) leveraging the phenomenon of quantum decoherence. Traditional QKD protocols, while theoretically secure, are susceptible to various attacks, often relying on the assumption of perfect quantum state preservation. This research proposes a framework for distributed key generation utilizing the inherent limitations imposed by quantum decoherence. The core concept involves encoding key information within quantum states that are deliberately designed to be vulnerable to decoherence. This vulnerability, rather than being a weakness, is exploited to introduce a level of inherent security, effectively masking the key's true value from an eavesdropper attempting to intercept and measure the quantum states. We explore the mathematical formalization of this process, detailing the generation of entangled states, the measurement protocols, and the key distillation process, all incorporating the effects of decoherence. The proposed system offers a potentially more robust defense against sophisticated attacks by introducing a naturally occurring element of uncertainty. This work provides a foundational understanding of utilizing decoherence as a key component within a QKD architecture. ---
