Yannick Meurice is a Professor at the University of Iowa. He obtained his PhD at U. C. Louvain-la-Neuve in 1985 under the supervision of Jacques Weyers and Gabriele Veneziano. He was a postdoc at CERN and Argonne National Laboratory and a visiting professor at CINVESTAV in Mexico City. He joined the faculty of the Department of Physics and Astronomy at the University of Iowa in 1990. His current work includes lattice gauge theory, tensor renormalization group methods, near conformal gauge theories, critical machine learning, quantum simulations with cold atoms and quantum computing. He is the PI of a multi-institutional DOE HEP QuantISED grant.

Summary:This book introduces quantum field theory models from a classical point of view. Practical applications are discussed, along with recent progress for quantum computations and quantum simulations experiments. New developments concerning discrete aspects of continuous symmetries and topological solutions in tensorial formulations of gauge theories are also reported. Quantum Field Theory: A Quantum Computation Approach requires no prior knowledge beyond undergraduate quantum mechanics and classical electrodynamics. With exercises involving Mathematica and Python with solutions provided, the book is an ideal guide for graduate students and researchers in high-energy, condensed matter and atomic physics.
Target Audience:Upper level undergraduate/graduate.
