Quantum Entanglement and Particle Scattering
Dr. Nathan Harshman
Assistant Professor & Chair of Physics Department
American University

When the state of a quantum system cannot be separated into the states of its constituents, we say the system is entangled. In some cases, the presence of entanglement means that measurements on different parts of a system have correlations stronger than can be explained by any purely classical theory. Einstein derisively called this effect “spooky action at a distance,” but now we know that entanglement is a hallmark of quantum mechanics. In this talk, I will investigate entanglement in particle systems. Different types of entanglement can occur in such systems, and dynamical processes can change the amount of entanglement.

In particular, I will look at how entanglement is generated between particles by scattering, the fundamental experimental paradigm for particle physics.
