Special EECS Seminar: Semiconductor Quantum Optics: New Frontiers for Information Processing and Precision Measurements
Speaker: Dirk Englund , Columbia University
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.
