Gentle Measurement of Quantum States and Differential Privacy
CMSA 20 Garden Street, Cambridge, MA, United StatesSpeaker: Scott Aaronson (University of Texas at Austin) Title: Gentle Measurement of Quantum States and Differential Privacy Abstract: I'll discuss a recent connection between two seemingly unrelated problems: how to measure a collection of quantum states without damaging them too much ("gentle measurement"), and how to provide statistical data without leaking too much about individuals ("differential privacy," an area of classical […]
A Compact, Logical Approach to Large-Market Analysis
CMSA 20 Garden Street, Cambridge, MA, United StatesSpeaker: Scott Duke Kominers (Harvard) Title: A Compact, Logical Approach to Large-Market Analysis Abstract: In game theory, we often use infinite models to represent "limit" settings, such as markets with a large number of agents or games with a long time horizon. Yet many game-theoretic models incorporate finiteness assumptions that, while introduced for simplicity, play a real role in the analysis. Here, we show […]
The Cubical Route to Understanding Groups
Speaker: Daniel Wise (McGill University) Title: The Cubical Route to Understanding Groups Abstract: Cube complexes have come to play an increasingly central role within geometric group theory, as their connection to right-angled Artin groups provides a powerful combinatorial bridge between geometry and algebra. This talk will introduce nonpositively curved cube complexes, and then describe the developments that culminated in the resolution of the virtual […]
