Description

The sampling of dense ensembles of self-avoiding polymers provides a paradigmatically hard problem in statistical mechanics and computational physics, even when resorting to minimalistic lattice models. In a series of recent studies, we addressed the question whether these computational limitations can be overcome by quantum annealers or by resorting quantum-inspired algorithms. We show that the reformulation of the sampling problems in terms of q-bits leads to a completely new field-theoretic approach with unexpected deep connections with lattice gauge theory. This greatly reduces the computational cost of sampling compact and/or topologically non-trivial ensembles even when implemented on a classical computer. We also compare the result of implementing our algorithms on classical and quantum hardware.
