Abstract

Quantum information transmission is subject to imperfections in communication processes and systems. These phenomena alter the original content due to decoherence and noise. However, suitable communication architectures incorporating quantum and classical redundancy can selectively remove these errors, boosting destructive interference. In this work, a selection of architectures based on path superposition or indefinite causal order were analyzed under appropriate configurations, alongside traditional methods such as classical redundancy, thus enhancing transmission. For that purpose, we examined a broad family of decoherent channels associated with the qubit chain transmission by passing through tailored arrangements or composite architectures of imperfect channels. The outcomes demonstrated that, when combined with traditional redundancy, these configurations could significantly improve the transmission across a substantial subset of the channels. For quantum key distribution purposes, two alternative bases were considered to encode the information chain. Because a control system must be introduced in the proposed architectures, two strategies for its disposal at the end of the communication process were compared: tracing and measurement. In addition, eavesdropping was also explored under a representative scenario, to quantify its impact on the most promising architecture analyzed. Thus, in terms of transmission quality and security, the analysis revealed significant advantages over direct transmission schemes.

Quantum Key Distribution Security Protocol Based on Quantum Decoherence

Jincheng Zhang

This paper investigates a novel quantum key distribution (QKD) protocol leveraging the principles of quantum decoherence to significantly enhance security against eavesdropping attacks. The core concept involves exploiting the inherent fragility of quantum states due to decoherence, introducing controlled noise to disrupt the eavesdropper's ability to intercept and decode the key. The proposed protocol, termed "Decoherence-Enhanced QKD" (DE-QKD), aims to bolster the security of existing QKD schemes by amplifying the impact of any attempt to observe the quantum key transmission. Mathematical formulations detail the key components, including the polarization encoding, the measurement process, and the key distillation steps, highlighting the protocol's robustness. The analysis demonstrates a substantial increase in security margins compared to conventional QKD protocols, particularly in the presence of imperfect devices and realistic noise conditions. This work contributes to the ongoing research in secure quantum communication and provides a practical pathway for deploying more resilient QKD systems. ---

Quantum-Inspired Cryptographic Protocols for Secure Communication in Noisy Channels

Jincheng Zhang

This paper investigates the application of quantum-inspired cryptographic protocols within the context of noisy communication channels. Traditional cryptographic methods often struggle against sophisticated attacks and are susceptible to degradation due to channel impairments. This research explores the utilization of principles derived from quantum mechanics, specifically superposition and uncertainty, to construct more resilient cryptographic schemes. The core idea is to mimic the inherent randomness and probabilistic nature of quantum systems to create protocols that are less vulnerable to conventional attacks and better equipped to handle the effects of noise. We present a framework for designing such protocols, focusing on key exchange and message encryption techniques. The proposed approach doesn't rely on actual quantum hardware but leverages mathematical models and algorithms inspired by quantum phenomena to achieve enhanced security. This work contributes to the growing field of post-quantum cryptography and offers a novel perspective on securing communication in environments where classical cryptographic assumptions may no longer hold. Specifically, we introduce a protocol based on the principle of superposition, where a key is represented as a probabilistic combination of multiple values, and a message is encoded as a superposition of possible states. The protocol incorporates a measurement process that leverages the inherent uncertainty of quantum mechanics to introduce randomness and thwart eavesdropping attempts. The proposed scheme is analyzed for its security properties, demonstrating its resilience against various attacks, including chosen-ciphertext attacks and differential cryptanalysis. The performance of the protocol is evaluated in terms of key generation time, encryption/decryption speed, and key size. The results demonstrate that the quantum-inspired protocol can achieve comparable security levels to traditional cryptographic schemes while offering improved robustness against channel noise.
