Learning Invariant Representations Under General Interventions on the Response

2023 · IEEE Journal on Selected Areas in Information Theory

It has become increasingly common nowadays to collect observations of feature and response pairs from different environments. As a consequence, one has to apply learned predictors to data with a different distribution due to distribution …

Noncommutativity as a Universal Characterization for Enhanced Quantum Metrology

2025 · Physical Review Letters

A central challenge in quantum metrology is to effectively harness quantum resources to surpass classical precision bounds. Although recent studies suggest that the indefinite causal order may enable sensitivities to attain the super-Heisenberg scaling, the …
