Joonwoo Bae
PhD 2007 from Universitat de Barcelona, Spain Institute de Ciencies Fotonique (ICFO), Spain
I’m interested in secure quantum communication and related areas including entanglement theory, quantum channels and protocols, and fundamental and theoretical tools in quantum information theory. I’m also interested in devising method of realizing building blocks of quantum information processing.
