- Title: Transport distance between Grover walks on graphs and coarse Ricci curvature
- Abstract:
In order to investigate relations between quantum walks and their underlying graphs, we introduce a coarse Ricci curvature for Grover walks. We use signed optimal transport theory to define this curvature. This talk is based on joint work with Chusei Kiumi.
