Stephen Wiesner

Stephen J. Wiesner was an American-Israeli research physicist, inventor and construction laborer. As a graduate student at Columbia University in New York in the late 1960s and early 1970s, he discovered several of the most important ideas in quantum information theory, including quantum money, quantum multiplexing and superdense coding. Although this work remained unpublished for over a decade, it circulated widely enough in manuscript form to stimulate the emergence of quantum information science in the 1980s and 1990s.
