In this talk, I'll present how my research group pioneered the use of the optical frequency comb in quantum optics to encode quantum information in continuous variables (CV), i.e. quantum fields rather than qubits, and generate record-size cluster entangled states, an essential resource for measurement-based, universal quantum computing. I will also present how photon-number-resolving measurement of CV cluster states can yield fault-tolerant qubit cluster states, our current research effort. Finally, I will outline the next crucial transition from bulk optics to integrated quantum photonics. Bio: Olivier Pfister received the B.S. in Physics from Université de Nice, France, in 1987, and the M.S. and the Ph.D. in Physics from Université Paris-Nord, France, in 1989 and 1993. In 1994, he was a lecturer at INM, Conservatoire National des Arts et Métiers, in Paris. He was then a research associate with John L. Hall at JILA, University of Colorado (1994-97) and with Daniel J. Gauthier at Duke University (1997-99). In 1999, he joined the faculty of the University of Virginia, where he is a professor of physics. Olivier Pfister is a fellow of the American Physical Society and a member of Optica, IEEE, and SPIE. His general research area is atomic, molecular, and optical physics, with past interests in quantum measurements at the ultimate precision, ultrahigh resolution laser spectroscopy, symmetry effects in small molecules, nonlinear optics for optical frequency chains, and two-photon lasers. His current research interest is quantum computing with light. He is a co-founder and CTO of quantum computing startup QC82, Inc.
