Due to the exponential growth of the Hilbert space dimension with system size, the
simulation of quantum many-body systems has remained a persistent challenge until today …

We consider two related tasks:(a) estimating a parameterisation of a given Gibbs state and
expectation values of Lipschitz observables on this state;(b) learning the expectation values …

Analyzing quantum many-body problems and elucidating the entangled structure of
quantum states is a significant challenge common to a wide range of fields. Recently, a …

Matrix quantum mechanics plays various important roles in theoretical physics, such as a
