Biography:

David Petrosyan is, since 2006, a Principal Researcher (tenured Associate Professor) at the Institute of Electronic Structure & Laser of the Foundation for Research & Technology - Hellas (Greece). He has been a Dale T. Mortensen Senior Fellow (Associate Professor) at the Aarhus Institute of Advanced Studies in 2014-2015, and since 2016 is a visiting Associate Professor at the Department of Physics and Astronomy of Aarhus University (Denmark). Since 2017 he is also a Mercator Fellow at the Center for Quantum Science, Physikalisches Institute, University of Tübingen (Germany). In 2014 he was awarded the Bessel Research Award of the Humboldt Foundation (Germany). He is an APS Outstanding Referee (2016) and is a Member of the Editorial Board of Physical Review A (since 2017).

David Petrosyan specializes in theoretical Quantum Optics and Quantum Information. His research interests include spin lattice models with cold atoms in optical lattices and interacting Rydberg atoms, quantum simulations of strongly interacting few- and many-body systems, quantum non-linear optics with single photons and coherent atomic ensembles, and physical implementations of quantum information processing and communication with optical, atomic, solid-state and hybrid systems. He has co-authored about 75 papers in refereed international journals, and a textbook on Fundamentals of Quantum Optics and Quantum Information, and has given 50 invited talks and seminars at international meeting and research centers.

Abstract:

Atoms in high-lying Rydberg states exhibit many remarkable features, including long lifetimes and giant polarizability. The resulting strong, long-range interactions between the Rydberg-state atoms can be turned on and off by the excitation and de-excitation lasers. Such systems can implement high-fidelity logic gates for digital quantum information processing. Moreover, arrays of Rydberg atoms are uniquely suited for realizing various spin-lattice models for analog quantum simulations of many-body physics. In this Colloquium, after a brief outline of the Rydberg atom physics, He will describe some recent experimental and theoretical studies concerning simulations of coherent and dissipative dynamics of many-body systems with laser controlled atoms in a lattice.
