Detecting quantum resources in mixed states
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...

Global Dualities in Quantum Integrable Systems and Markov Processes
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...

Video Generation Models are General-Purpose Vision Learners
时 间：10:00-11:00, Aug 7, 2026 (Fri)地 点：https://meeting.tencent.com/dm/z9BkdA8pj32P (https://meeting.tencent.com/dm/z9BkdA8pj32P)内容：Driven by next-token prediction, NLP shifted from task-specific models into powerful generalist foundation models. What, then, is the equivalent catalyst needed to achieve a general-purpose model in computer vision?In this talk, we contend that large-sca...

Building Commonsense for General-Purpose Robots
时 间：11:00-12:00, Aug 6, 2026 (Thu)地 点：https://meeting.tencent.com/dm/RB08CDbR31ou (https://meeting.tencent.com/dm/RB08CDbR31ou)内容：Robots operating in real-world environments must handle open-ended tasks, novel objects, and instructions from non-expert users. However, current systems often fail to generalize beyond their training data because they lack commonsense knowledge about th...

Hong-Ou-Mandel interference between temporally non-overlapping optical pulses and its application to quantum communication
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...

Quantum circuit as a lens into quantum phases and phase transitions
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...
