Phase shadow: A noise-tolerant path to global quantum property estimation
演讲人：周游 [复旦大学]时 间：16:00-18:00, Mar 31, 2026 (Tue)地 点：RM S327, MMW Building内容：Measuring global quantum properties-such as the fidelity to complex multipartite states-is both an essential and experimentally challenging task. Classical shadow estimation offers favorable sample complexity, but typically relies on many-qubit circuits that are difficult to realize on current pla...

面向结构化预测的Boosting：几何结构中的稳定性
演讲人：Jian Qian [The University of Hong Kong]时 间： 14:00-15:00, Mar 24, 2026 (Tue)地 点： 清华大学吕大龙楼806内容：尽管Boosting方法在结构化预测中被广泛应用，但对于超越标量损失的聚合方法，目前仍缺乏统一而系统的理论理解。在本报告中，我将介绍我们近期关于向量值预测（vector-valued prediction）与条件密度估计（conditional density estimation）的研究工作，并讨论在一般散度（divergence）下的理论框...

Generative Social Choice
演讲人：Ariel Procaccia [Harvard University] 时间：09:45-12:30, Mar 16, 2026 (Mon)地点： Lecture Hall, FIT Building内容：How should one design collective decision-making processes capable of handling enormous sets of alternatives like all possible policies, bills, or statements? I argue that this challenge can be addressed through a framework called generative social choice, which fuses the rig...

A Fiat–Shamir Transformation From Duplex Sponges
演讲人：Michele Orrù [CNRS] 时间： 14:00-15:00, Mar 12, 2026 (Thu)地点： RM 1-222, FIT Building内容：We study a new Fiat-Shamir transformation based on an ideal permutation that minimizes permutation calls and aligns more closely with deployed systems. We show concrete bounds for soundness, knowledge soundness, and zero knowledge, revealing that indifferentiability -- the standard notion used ...

Scaling Trust without Trusting
演讲人：Binyi Chen时间：14:00-15:00, Feb 28, 2026 (Sat)地点： RM 1-222, FIT Building内容：In an era of AI and digitalization, we face a dual challenge in building trust while preserving privacy. For example, social platforms are flooded with unverifiable AI-generated content, and online services require users to excessively expose their personal data. Zero-Knowledge Succinct Proofs (ZK-SNARKs) ...
