IIHE invited seminar: Exploring quantum entanglement at hadron colliders using top quarks at the ATLAS experiment (James Howarth)

Friday 22 Mar 2024, 14:30 → 16:00 Europe/Brussels

G/1-G.1.03 - J. Sacton (Building G)

Abstract:
ATLAS recently observed quantum entanglement in pairs of top quarks using 13 TeV data, the first time that entanglement has been observed in fundamental quarks and at the highest ever energy scales. In this seminar I will explain how this ground breaking measurement was achieved, how it highlights limitations in our current state-of-the-art Monte Carlo simulations, and the implications of the result in the wider context of quantum information. I will also explain what direction this exciting new field of study at collider experiments might take and highlight new opportunities for collaborations between quantum information and collider physics.

Dr James (Jay) Howarth is a Lecturer at the University of Glasgow and Royal Society University Research Fellow. He obtained his PhD at the University of Manchester in 2013, followed by a research fellowship at DESY and a postdoctoral research position at the University of Manchester. His research focuses on top quark physics in general, particularly on the properties of top quarks at hadron colliders and is a member of the ATLAS collaboration.
