Abstract

This paper explores a semi-device-independent approach to multiparty quantum key distribution (QKD) in the asymptotic limit. The authors provide a framework for secure communication in multiparty quantum networks, demonstrating the feasibility and advantages of this approach in high-dimensional quantum systems.

Key Contributions

  • Semi-device-independent QKD: Introduced a framework for multiparty QKD with reduced trust assumptions.
  • Asymptotic Limit Analysis: Provided theoretical insights into the performance of QKD in the asymptotic limit.
  • Multiparty Security: Demonstrated the feasibility of secure communication in multiparty quantum networks.

Significance

This research advances the field of quantum cryptography by addressing the challenges of multiparty communication in high-dimensional quantum systems. The proposed semi-device-independent approach reduces trust assumptions while maintaining security, making it a significant step forward in practical quantum communication.
