Note on Strong Quantum Markov Properties

Chi-Fang Chen

Quantum many-body Gibbs states satisfy an approximate local Markov property~\cite{chen2025GibbsMarkov}: local noise can be approximately recovered by a quasi-local recovery map, an…

Efficiently estimating quantum thermal properties from exponentially fewer samples

Chi-Fang Chen, András Gilyén

We present an efficient protocol for estimating $M$ observables to precision $ε$ from only $O (lo g (M) / ε^{2})$ copies of a Gibbs state $ρ\propto\exp(-βH…
