Recent Advances in Fast Graph Algorithms: Combinatorial Techniques for Path and Flow Problems
时 间：14:00-15:00, Jun 29, 2026 (Mon)地 点：RM 1-222, FIT Building内容：We will discuss recent algorithmic advances for fundamental graph problems, including negative-weight shortest paths, maximum flow, and minimum-cost flow. Classical textbook-style algorithms, such as Bellman-Ford and push-relabel, often lead to \(O(mn)\)-type running times. In recent years, however, there has been trem...

Reconfigurable Dissipative Entanglement between Many Spin Ensembles: From Robust Quantum Sensing to Many-Body State Engineering （Online talk）
时 间：10:30-11:30, Jun 11, 2026 (Thu)地 点：线上报告 (腾讯会议：963-955-107)内容：An attractive approach for stabilizing entangled many-body spin states is to employ engineered dissipation. Most existing proposals either target relatively simple collective spin states or require numerous independent and complex dissipative processes. Here, we show a surprisingly versatile scheme [1] for ma...
