Quantum Information at the Electron-Ion Collider
Kun Cheng, Tao Han, Sokratis Trifinopoulos
We investigate quantum-information-theoretic observables in electron-proton scattering at the Electron-Ion Collider (EIC). Our analysis focuses on entanglement and magic, two compl…
Collider probes of baryogenesis with maximal CP asymmetry
Debasish Borah, Kun Cheng, Arnab Dasgupta +2
We propose a novel collider probe of baryogenesis at TeV scale by measuring decay asymmetries into particle and anti-particle final states. Motivated by the idea of Dirac leptogene…
Quantum Tomography in Neutral Meson and Antimeson Systems
Kun Cheng, Tao Han, Matthew Low +1
The flavor space of particles produced in collider environments contains informative quantum correlations. We present a systematic approach for constructing the complete flavor den…
Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics
Yoav Afik, Federica Fabbri, Matthew Low +68
Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…
Maximizing the Azimuthal-Angle Correlation in the Decay of Vector Boson Pairs
Kun Cheng, Yi-Jing Fang, Tao Han +1
Spin correlation observables of particles produced at colliders generally depend on the coordinate basis. While spin correlations and their associated basis dependence have been st…
Quantum Tomography at Colliders: With or Without Decays
Kun Cheng, Tao Han, Matthew Low
The interpretation of groups of particle spins at colliders as quantum states has opened up the possibility of using colliders for quantum information. While most efforts have focu…
