Week 03 - Quantum Technology and Hong Kong’s Cybersecurity in Quantum Era

Topic Overview:

Quantum technology for cybersecurity refers to the city's race to protect its critical digital infrastructure, especially its banking and financial sectors, from both future quantum computing attacks and emerging quantum-based hacking threats. This effort translates into two main technological priorities: quantum key distribution (量子加密通信) and post-quantum cryptography (後量子密碼學). The QKD uses the principles of quantum mechanics to transmit data securely. This talk is organized into two main parts. The first part introduces fundamental concepts in quantum physics and quantum information. The second part focuses on recent advances in QKD and PQC technologies, examines their potential applications in future communication networks, and discusses broader implications for practical deployment and system integration. Finally, the talk concludes with a forward-looking perspective on the development of quantum technologies, offering insights and recommendations for strengthening cybersecurity strategies and network infrastructure in the city.
