Daniel Loss received his Diploma (1983) and Ph.D. (1985) in theoretical physics at the University of Zürich. From 1989 to 1991 he worked as a postdoc at the University of Illinois at Urbana-Champaign with A. J. Leggett, and from 1991 to 1993 at the IBM T.J. Watson Research Center, NY. In 1993 he joined the faculty of Simon Fraser University in Vancouver, and then returned to Switzerland in 1996 to become Professor of Physics at the University of Basel. His research interests include quantum coherence and spin physics in semiconducting and magnetic nanostructures, and quantum computing. In 2000 he became an APS Fellow and in 2005 he received the Humboldt Research Prize.
Quantum measurements are conventionally thought of as irretrievably “collapsing” a wave function to the observed state. However, experiments with superconducting qubits show that the partial collapse resulting from a weak continuous measurement can be restored.
