4540. Quantum State Distinguishability, Antidistinguishability, and Exclusion

Invited Speaker / Conférencier(ère) invité(e)

A set of pure quantum states is said to be "distinguishable" if upon sampling one at random, there exists a measurement to perfectly determine which state was sampled. It is well-known that a set is distinguishable if and only if its members are mutually orthogonal. In this talk, we explore some variants of distinguishability such as "antidistinguishability", which asks for the existence of a...

4563. Paradoxes and Probabilities: Revisiting quantum nonlocality in the graphical formalism of causal inference

Division for Quantum Information / Division de l'information quantique (DQI / DIQ)

Invited Speaker / Conférencier(ère) invité(e)

This talk aims to reveal the causal reasoning that underpins both the foundations of quantum theory and the superficially-unrelated data science framework of graphical models, also known as Bayesian networks. We will connect quantum nonlocality, as characterized by Bell's Theorem, with the idea of causal discovery in the presence of latent confounders. Understanding this relationship provides...
