时 间：11:00-12:00, Aug 13, 2026 (Thu)地 点：RM S527, MMW Building内容：Detecting quantum resources, especially in mixed quantum states, is a highly challenging task. Starting from the widely-used concept of resource witnesses, we propose a framework that systematically generate analytical and experimentally accessible criteria based on a single witness and a group of free unitaries.Our co...
时 间：11:00-12:00, Aug 21, 2026 (Fri)地 点：腾讯会议：188-585-149（会议链接：https://meeting.tencent.com/dm/ueSfCeE8ENCB）内容：Duality transformations reveal unexpected equivalences between seemingly distinct models. We introduce a concept of global duality, in which a duality operator intertwines two one-dimensional local Hamiltonians via generalised exchange relations, in contrast to lo...
时 间：10:30-11:30, Aug 5, 2026 (Wed)地 点：RM S327, MMW Building内容：Hong-Ou-Mandel (HOM) interference between two indistinguishable photons is a cornerstone of photonic quantum information science and underlies Bell-state measurement (BSM) in measurement-device-independent quantum key distribution (MDI-QKD). Although HOM interference is often associated with photon bunching that requires...
时 间：17:00-18:00, July 30, 2026 (Thu)地 点：RM 1-222, FIT Building内容：Quantum systems host fascinating phases like superconductivity, quantum Hall, topological order, etc that have no classical counterpart. Understanding what quantum phases exist and how phase transitions happen between them is the ultimate goal of condensed matter. But this is notoriously hard, especially in systems w...
时 间：16:00-16:45, Jul 24, 2026 (Fri)地 点：RM 1-222, FIT Building内容：We investigate the structural properties, including isomerization, and melting behavior of two-dimensional ion crystals in an RF trap, focusing on the effects of ion temperature and trap potential anisotropy. We identify distinct crystal structures that form under varying trapping conditions and temperatures through ex...
时 间：10:00-10:45, Jul 24, 2026 (Fri)地 点：RM 1-222, FIT Building内容：Understanding how molecular vibrations afiect charge and energy transfer in complex chemical and biological systems requires modeling the interactions among the electronic, spin, and vibrational degrees of freedom, which cannot be treated independently, especially when the Born-Oppenheimer approximation breaks down. Tr...
