Tensor networks
Tensor network study of a strongly correlated quantum system.
Tensor networks develop analytical and numerical methods for the classical description of complex quantum many-body systems. Our research advances tensor network techniques, including matrix product states and projected entangled pair states for two-dimensional systems, to study strongly correlated quantum matter and its dynamics. We also develop efficient methods for the classical simulation of noisy quantum circuits, with the goal of identifying when quantum computations can be simulated efficiently on classical computers and thereby sharpening the boundary between classical and genuinely quantum computational advantages.
