We show that, under the linear conditional mean condit...

CAOS: Conformal Aggregation of One-Shot Predictors
arXiv:2601.05219v2 Announce Type: replace Abstract: One-shot prediction enables rapid adaptation of pretrained foundation models to new tasks using only one labeled example, but lacks principled uncertainty quantification. While conformal prediction provides finite-sample coverage guarantees, standard split conformal m...

Probing Entanglement and Symmetries in Random States Using a Superconducting Quantum Processor
arXiv:2601.22224v1 Announce Type: new Abstract: Quantum many-body systems display an extraordinary degree of complexity, yet many of their features are universal: they depend not on microscopic details, but on a few fundamental physical aspects such as symmetries. A central challenge is to distill these universal chara...
