Walter Vinci

Walter Vinci received his Ph.D. in Physics from the University of Pisa. During his Ph.D. research thesis and first postdoc at the University of Minnesota, he studied supersymmetric models for particle confinement involving topological solitons. His research also involved the study of solitonic structures in condensed matter systems. As a Research Associate at the University of Southern California, his research activities focus on adiabatic quantum computation, quantum and classical optimization, and open system quantum dynamics. He is specially interested in the use of quantum annealing for feature recognition and machine learning, the theoretical and experimental characterization of quantum annealing devices, and the development of error correcting codes.
