Three Facets of Understanding Pre-training: Loss, Inductive Bias, and Implicit Bias
AI is undergoing a paradigm shift with the rise of models pre-trained with self-supervisions and then adapted to a wide range of downstream tasks. However, their working largely remains a mystery; cla...

Coherent coupling of trapped ion mechanical oscillators for quantum information processing
I will present our recent progress in the coherent coupling of spectrally separated harmonic modes of motion of a trapped ion crystal and its applications. We realize high-fidelity coherent exchange o...
