This presentation will explore the potential threats posed by quantum computer technology to the security of mobile communication identities and emphasize the importance of establishing quantum-secure networks. We will begin by introducing the current status of quantum-secure networks in the 6G international standards and analyzing technologies for quantum-resistant mobile communication networks. Next, we will demonstrate how generative AI assists in research related to IBM quantum computers and quantum-secure networks, sharing the latest research findings and practical experiences. Additionally, the audience will learn about practicing quantum computing on the Google Colab and/or GitHub Codespace platforms and how to use IBM quantum computers for computation. Finally, we will arrange a live demonstration to show how to use Qiskit on Google Colab and/or GitHub Codespace for quantum circuit design and simulation. The audience will gain a comprehensive understanding of the latest developments in quantum computing and network security and acquire practical operational experience to prepare for future technological challenges.
