A graphical diagnostic of topological order using ZX calculus
Publications
Working with researchers at the CNRS and the Donostia International Physics Center, we developed a graphical way to identify topological order using ZX calculus, without relying on traditional entanglement-entropy calculations. Understanding and diagnosing these robust forms of quantum order is an important step toward controlling complex quantum systems, helping develop the foundations for fault-tolerant quantum computation and the quantum resources needed for useful computation.
