Efficient quantum Gibbs sampling of stabilizer codes using hybrid computation
Ivan H. C. Shum, Angela Capel
We present hybrid Gibbs sampling algorithms for the stabilizer code Hamiltonians of the rotated surface code and the toric code with only local quantum algorithms, using …

Conditional Independence of 1D Gibbs States with Applications to Efficient Learning
Ãlvaro M. Alhambra, Ãngela Capel, Paul Gondolf +2
We show that spin chains in thermal equilibrium have a correlation structure in which individual regions are strongly correlated at most with their near vicinity. We quantify this…

Continuity bounds for quantum entropies arising from a fundamental entropic inequality
Koenraad Audenaert, Bjarne Bergh, Nilanjana Datta +3
We establish a tight upper bound for the difference in von Neumann entropies between two quantum states, and . This bound is expressed in terms of the von Neumann entr…
