Enabling Secure and Trustworthy Quantum Networks: Current State-of-the-Art, Key Challenges, and Potential Solutions

Quantum networks hold the promise of enabling secure and trustworthy communication and computation. However, they also pose significant challenges in terms of security, privacy, and trust. In this paper, we have explored the current state-of-the-art in the field of quantum network security, privacy, and trust, with a focus on quantum key distribution, quantum-resistant cryptography, quantum hacking, trust establishment, and privacy-enhancing technologies. We have identified key challenges and open research questions in these areas, and presented potential solutions to enable the realization of secure and trustworthy quantum networks. As quantum networks continue to evolve, addressing these challenges will be crucial to realizing their full potential for secure communication and computation.
