The International Symposium on Recent Advances in Quantum Science and Technology 2026, hosted by VNUHCM-US, convenes prominent researchers to examine the pivotal challenges and opportunities characterizing the second quantum revolution. The scientific program is structured around three core disciplines: Quantum Materials, which investigates the synthesis and characterization of novel states of matter essential for next-generation hardware; Quantum Optics, focusing on light-matter interactions and photon manipulation to advance sensing and communication networks; and Quantum Computing, dedicated to the theoretical and practical evolution of quantum algorithms and quantum AI. Through the integration of these distinct research streams, the symposium seeks to expedite the translation of quantum principles from theoretical concepts into viable, real-world applications.
