Nathan Harshman Professor Department of Physics

PhD, Theoretical Particle Physics, University of Texas at Austin
BS, Double major: Physics and English, Duke University

Professor Harshman pursues research in theoretical physics, focusing his studies on the intersection of quantum information theory and particle physics. Entanglement is a fundamental resource for many future quantum information processing applications like quantum computation and encryption, and Professor Harshman explores how to quantify and detect entanglement in composite particle systems such as molecules and atoms and fundamental particles like electrons and photons. He teaches across the physics curriculum from introductory courses to independent studies on advanced topics.
