Enhancing Trustworthiness in the Quantum Internet through Super-Additivity and Superposed Trajectories


Core Concepts
Leveraging quantum properties such as super-additivity and superposed trajectories can significantly improve the trustworthiness and reliability of communication protocols in the quantum internet, outperforming classical approaches.
Abstract
The paper explores the use of quantum-assisted mechanisms to enhance the trustworthiness of communication networks, particularly in the context of an Antarctic telemetry service deployed over a wireless network. The key highlights are: Trustworthiness in a communication network is essential for reliable data exchange, especially in harsh environments like Antarctica. Redundancy in measuring spots and communication paths is a common approach to increase trustworthiness. Existing algorithms for managing redundancy often involve extensive message exchanges, which can degrade performance in bandwidth-limited networks. The authors propose leveraging quantum-assisted mechanisms to address this issue. The paper explores the use of quantum super-additivity and superposed quantum trajectories to improve the performance of the social trustworthiness layer, which sets an upper bound on the Successful Transactions Rate (STR) in classical systems. Simulation results show that the proposed quantum-assisted mechanisms can increase the system's STR by up to 28% compared to classical approaches, particularly in scenarios with a larger number of redundant sensors. The quantum social trustworthiness mode, which incorporates super-additivity and superposed trajectories, outperforms the reference classical social trustworthiness layer by over 27% in the simulated scenarios. The benefits of the quantum-assisted mechanisms become more pronounced as the number of redundant sensors increases, enabling broader deployment scenarios with more sensors and measuring spots. Overall, the paper demonstrates the potential of quantum-assisted techniques to significantly enhance the trustworthiness and reliability of communication networks, particularly in challenging environments like Antarctica.
