Quantum Observables for Collider Physics 2025

7 Apr 2025, 13:30 → 10 Apr 2025, 14:00 Europe/Rome

Galileo Galilei Institute for Theoretical Physics

Welcome to the 2025 edition of the "Quantum observables for Collider Physiscs" at GGI!

The workshop aims at gathering theorists as well as experimentalist interested on measuring quantum information observables, such as magic, entanglement anbell Inequality Violation, on particles created at colliders and then use these new observables as an innovative direction to probe fundamental interactions. The programme includes discussion on the first experimental results obtained in this field, on the implications of these new observables for new physics searches, both within and beyond quantum mechanics, feasibility studies for multiple final state, in current and future colliders, and discussion on the limits of these measurements. The programme will also include lectures and overview talks aimed to explore the connection between quantum information, technology and high energy physics. 

More information on the organisation is available in the timetable and travel and accomodation.
