Digitized counterdiabatic quantum critical dynamics
We experimentally demonstrate that a digitized counterdiabatic quantum protocol reduces the number of topological defects created during a fast quench across a quantum phase transition. To show this, we perform quantum simulations of one- and two-dim...

Bounding the Error of Value Functions in Sobolev Norm Yields Bounds on Suboptimality of Controller Performance
Optimal feedback controllers for nonlinear systems can be derived by solving the Hamilton-Jacobi-Bellman (HJB) equation. However, because the HJB is a nonlinear partial differential equation, numerical methods typically provide only approximate solut...
