Certified algorithms for quantum Hamiltonian learning via energy-entropy inequalities
Adam Artymowicz, Hamza Fawzi, Omar Fawzi +1
We consider the problem of learning the Hamiltonian of a quantum system from estimates of Gibbs-state expectation values. Various methods for achieving this task were proposed rece…
Tensor Network Python (TeNPy) version 1
Johannes Hauschild, Jakob Unfried, Sajant Anand +27
TeNPy (short for 'Tensor Network Python') is a python library for the simulation of strongly correlated quantum systems with tensor networks. The philosophy of this library is to a…
A Faster Algorithm for the Free Energy in One-Dimensional Quantum Systems
Samuel O. Scalet
We consider the problem of approximating the free energy density of a translation-invariant, one-dimensional quantum spin system with finite range. While the complexity of this pro…
Conditional Independence of 1D Gibbs States with Applications to Efficient Learning
Álvaro M. Alhambra, Ángela 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…
