Verifiable quantum advantage with peaked circuits
演讲人：张宇轩时间：10:00-11:30, Jan 15, 2026 (Thu)地点： 蒙民伟科技大楼南楼527会议室内容：Over a decade after its proposal, the idea of using quantum computers to sample hard distributions has remained a key path to demonstrating quantum advantage. Yet a severe drawback remains: the anti-concentrated distributions believed to be hard to classically simulate are typically hard to verify without...

Rationality of multi-agent learning and uncertainty quantification for the generative models
演讲人：Yian Ma (马易安) [University of California, San Diego]时间：13:30-15:00, Dec 26, 2025 (Fri)地点：RM 1-222, FIT Building内容：In the first part of the talk, I will discuss an interesting phenomenon in multiagent learning, that the mixed Nash equilibria are uniformly stable if and only if they are collectively rational. This justifies the effusive use of multi-agent learning systems and r...
