Faculty in Quantum Information Science

Stephen E. Harris
Professor of Electrical Engineering and Applied Physics
Barbara and Kenneth Oshman Chair in Electrical Engineering

Our group has two projects: 1) The first is aimed at the synthesis of single-cycle optical wave forms, and more generally at the synthesis of optical waveforms of arbitrary shape. This is done by using a Raman source that has approximately four octaves of optical bandwidth. 2) We are interested in synthesizing the quantum waveforms of spontaneously emitted and entangled biphotons. As an example, one may generate entangled photons that have opposing chirps, and then use group velocity dispersion at either wavelength to make ultra-short, and in effect, high power photons.

Hideo Mabuchi
Professor of Applied Physics

Our group works in physical measurement and control, with current emphasis on the development and application of practical methodologies for the study of hypersensitive quantum systems and context-sensitive biophysical phenomena. The most distinctive aspects of our scientific research emerge from a synthesis of theoretical physics, systems engineering and advanced experimental technique.

Yoshihisa Yamamoto
Professor of Applied Physics and of Electrical Engineering

Experimental and theoretical quantum optics with a special emphasis on quantum information science applications. Generation and detection of single photons and entangled photons, quantum key distribution based on differential phase shift (DPS) protocol, quantum repeater based on cavity QED network connected by coherent state bus and quantum simulation of many body problems based on exciton polariton and two-dimensional electron gas systems.

Bernardo A. Huberman
Consulting Professor of Applied Physics
Senior HP Fellow
Director, Information Dynamics Laboratory, HP Labs

I'm interested in the dynamics of information and how it flows within networks. As part of my research we have designed and implemented a globally distributed computer network that allocates resources by auctioning off computons, bundles of cpu, storage and bandwidth. The other aspect of this work involves designing and testing in the laboratory mechanisms for discovering and aggregating that information using economic incentives. Examples are the discovery of social networks from patterns in email exchanges, the prediction of uncertain events using groups of people within a market setting, and more recently the economics of attention.

Scanning SQUID microscopy: For the past dozen years I have developed the technique of scanning SQUID microscopy and used the resulting novel instruments for fundamental studies.
