Quantum Tomography of Fermion Pairs in Collisions: Longitudinal Beam Polarization Effects
Yu-Chen Guo, Tao Han, Matthew Low +1
We present a quantum tomography study of fermion pair production at future colliders, emphasizing how longitudinal beam polarization controls the two-qubit spin density ma…
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…
Colorful Particle Production at High-Energy Muon Colliders
Tao Han, Matthew Low, Tong Arthur Wu +1
A high-energy collider provides a wide variety of mechanisms for the production of new heavy particles. While the reach for such particles via the direct annihilation of $…
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…
Entanglement and Bell Nonlocality in at the BEPC
Tao Han, Matthew Low, Youle Su
Quantum entanglement and Bell nonlocality are two phenomena that occur only in quantum systems. In both cases, these are correlations between two subsystems that are classically ab…
