Special EECS Seminar: Semiconductor Quantum Optics: New Frontiers for Information Processing and Precision Measurements

Speaker: Dirk Englund , Columbia University
Date: March 5 2012
Time: 3:00PM to 4:00PM
Location: GRIER A CONFERENCE ROOM: 34-401A
Host: Marc Baldo, EECS

Abstract: The field of quantum optics has not only shaped fundamental physics, but also contributed to radically new quantum technologies in communications, computation, and metrology. A major goal of semiconductor quantum optics is to realize these technologies in scalable semiconductor systems, building on the dramatic advances of semiconductor technology in past decades. In the first part of this talk, I will describe our recent work towards photonic integrated chips to control information in the form of photons and electron spins in InAs/GaAs quantum dots and diamond nitrogen vacancy color centers. This architecture now enables efficient generation and transport of single photons, nonlinear optical interactions at the single photon level, and new types of energy-efficient, high-speed classical information processing devices. In the second part of the talk, I will discuss new directions in precision measurements, including the development of electron spin-based optical biosensors.

Bio: Dirk Englund received his BS in Physics from Caltech in 2002. Following a year at the TU Eindhoven, where he studied spintronics as a Fulbright Scholar, he completed his PhD in Applied Physics and MS in Electrical Engineering from Stanford University in 2008. His postdoctoral work at Harvard centered on experimental and theoretical quantum optics in the groups of Mikhail Lukin and Hongkun Park. At Columbia University, his research leverages semiconductor technology to build scalable quantum devices for information processing and metrology. His recognitions include the 2011 Presidential Early Career Award for Scientists and Engineers, the 2011 Sloan Research Fellowship in Physics, and the 2008 Intelligence Community (IC) Postdoctoral Fellowship. He has published over 40 journal articles and four book chapters.
