Decoherence and More Coherence in the Radiative Decay of the Boson
Kun Cheng, Tao Han, Harman Singh +1
The paper analytically studies how photon emission in the radiative decay Z → τ⁻τ⁺γ affects the spin entanglement of the τ pair, showing that the photon can cause either decoherenc…
Quantum Information of Photon Pairs at Lepton Colliders
Kun Cheng, Tao Han, Guanghui Li +1
Photon pairs have provided an ideal laboratory for exploring entanglement and Bell inequality violation in low-energy experiments. Extending such studies to high-energy colliders i…
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…
Optimizing Entanglement and Bell Inequality Violation in Top Anti-Top Events
Kun Cheng, Tao Han, Matthew Low
A top quark and an anti-top quark produced together at colliders have correlated spins. These spins constitute a quantum state that can exhibit entanglement and violate Bell's ineq…
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…
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…
