Ravines in quantum cost landscapes: opportunities for improved VQA predictions
Felix J. Beckmann, João F. Bravo
The geometric and topological structure of quantum cost landscapes (QCLs) governs the optimization and thus the predictive power of variational quantum algorithms (VQAs). We systematically analyze ravines - low-cost paths connecting local minima - using an adapted version of the…
