Decoherence and More Coherence in the Radiative Decay of the Boson
Kun Cheng, Tao Han, Harman Singh +1
Final state radiation in collider processes can be interpreted as interactions with unobserved degrees of freedom and is often discussed within the context of decoherence of an ent…
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…
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…
Entanglement and Bell Nonlocality in at the LHC using Machine Learning for Neutrino Reconstruction
Yulei Zhang, Bai-Hong Zhou, Qi-Bin Liu +5
Experiments at the CERN Large Hadron Collider (LHC) have accumulated an unprecedented amount of data corresponding to a large variety of quantum states. Although searching for new…
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…
Measuring Quantum Discord at the LHC
Tao Han, Matthew Low, Navin McGinnis +1
There has been an increasing interest in exploring quantities associated with quantum information at colliders. We perform a detailed analysis describing how to measure the quantum…
Electroweak Symmetry Restoration and Radiation Amplitude Zeros
Rodolfo Capdevilla, Tao Han
In high-energy collisions far above the electroweak scale, the effects of electroweak symmetry breaking are expected to become parametrically small . This defines the…
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…
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…
