Tudor Stanescu

Biography

Prof. Stanescu received a B.S. in Physics from the University of Bucharest, Romania, in 1994 and a Ph.D. in Theoretical Physics from the University of Illinois at Urbana Champaign in 2002. He was a Postdoctoral Fellow at Rutgers University and at the University of Maryland from 2003 to 2009. He joined the Department of Physics and Astronomy at West Virginia University in Fall 2009.  

Research

Prof. Stanescu’s research interests encompass a variety of topics in theoretical condensed matter physics including topological insulators and superconductors, topological quantum computation, ultra-cold atom systems in optical lattices, and strongly correlated materials, such as, for example, cuprate high temperature superconductors. His research uses a combination of analytical and numerical tools and focusses on understanding the emergence of exotic states of matter in solid state and cold atom structures, for example, topological superconducting phases that host Majorana zero modes, and on investigating the possibilities of exploiting these states as physical platforms for quantum computation.

Introduction to Topological Quantum Matter & Quantum Computation

The book provides a “travel guide” for the newcomer to the field of quantum topology and quantum computation – a new, exciting, and rapidly developing area that integrates ideas from physics, mathematics, and computer science. The specific topics addressed in this book range from the classification of topological quantum phases and the discussion of specific topological quantum models, to introductory concepts in quantum information theory and quantum computation, including fault-tolerant topological quantum computation with anyons.
