Quantum entanglement in top-quark pair production


Dear colleagues,

we would like to invite you to the seminar of Division of Elementary Particle Physics of Institute of Physics, presented by Dr. Roman Lysák.

For more info, please see invitation.



The quantum entanglement is one of the most characteristic features of quantum mechanics. It was observed in multiple systems, typically at low energies. In recent years, there have been proposals to study this phenomenon at the high energy particle colliders. In this talk, I report on the observation of quantum entanglement in top-quark pair production within the ATLAS experiment at the Large Hadron Collider at CERN. This potentially opens up a new avenue for quantum information measurements at the colliders, for example, the measurement of Bell inequality violation.
