Entanglement Detection Via Frank-Wolfe Algorithms
This project applies a Frank-Wolfe-based approach for separability certification and entanglement detection of multipartite quantum states. The method is further exploited to derive entanglement witnesses for cases of incomplete state characterisation, often encountered in experiments.
