Abstract:
Discover the cutting-edge intersection of quantum information and particle physics: learn how the recent detection of quantum entanglement in top quark pairs by ATLAS and CMS is opening new frontiers at the LHC.
Recently, the ATLAS and CMS Collaborations made the first observation of quantum entanglement in top quark pairs, marking an exciting milestone at the LHC. At first glance, this might seem unsurprising - after all, the Standard Model is a quantum field theory. So why is this discovery generating so much buzz? In this seminar, I will unpack the technical challenges behind this measurement and illustrate how quantum information concepts can provide new tools for high-energy physics, and vice versa. I will also discuss the unexpected observation of toponium formation at the LHC, placing it in the broader phenomenological context: what makes modeling top quark pair production and decay so challenging? Finally, I will explore the prospects for the upcoming Run 3 dataset and the High-Luminosity LHC era, highlighting how quantum information techniques may open entirely new avenues in precision measurements and the emerging subfield of quantum information at the LHC.
The seminar will be held in the Dvořák hall, FZU, Pod Vodárenskou věží 1, Prague.
