Kun Cheng,PITT, [HET Seminar] Quantum State Tomography at Colliders

Thursday 15 Jan 2026, 11:00 → 13:00 US/Eastern

Small Seminar Room

Abstract: Some of the most astonishing and prominent properties of quantum mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in low-energy laboratory setups.  In recent years, the observation of entanglement and studies of other quantum correlations in collider experiments mark a significant step toward integrating quantum information with high-energy physics.  Particle colliders provide vast number of events and rich quantum systems for quantum information studies, and the first step of these study is to reconstruct the density matrix of the system, known as quantum state tomography. In this talk, I will first revisit the standard steps of quantum tomography for the spin states of massive particles, then I will introduce recent developments of quantum tomography in other systems such as spin states of quark pairs and the flavor states of neutral meson pairs.
