Universal Sequential Changepoint Detection of Quantum Observables via Classical Shadows
Matteo Zecchin, Osvaldo Simeone, Aaditya Ramdas
We study sequential quantum changepoint detection in settings where the pre- and post-change regimes are specified through constraints on the expectation values of a finite set of…

Quantum Sequential Universal Hypothesis Testing
Matteo Zecchin, Osvaldo Simeone, Aaditya Ramdas
Quantum hypothesis testing (QHT) concerns the statistical inference of unknown quantum states. In the general setting of composite hypotheses, the goal of QHT is to determine wheth…
