This monthly talk for ThaiYQ2025 & IYQ2025 will focus on generating random numbers, which play a crucial role in many scientific applications, presented by an active researcher, Dr. Xing Lin from Hong Kong. Unlike pseudo-random number generators, quantum devices can produce truly random numbers based on the fundamental laws of quantum mechanics.

However, information-theoretically secure random number generation is typically predicated on idealized device models, which may not accurately reflect real-world implementations. To address this gap, he has introduced several quantum random number generation protocols that do not rely on detailed characterization of the devices. In this talk, he will first provide an overview of the development and research progress in quantum random number generation. He will then introduce our recent works in this area, followed by a discussion of future directions for quantum random number generation.
