Stable and efficient differentiation of tensor network algorithms
Gradient-based optimization methods are the established state-of-the-art paradigm to study strongly entangled quantum systems in two dimensions with projected entangled pair states. However, the key ingredient, the gradient itself, has proven challenging to calculate accurately and reliably in the c...
