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…
-incidental -naturalness
Brian Batell, Akshay Ghalsasi, Wenjie Huang +1
-naturalness is a novel solution to the electroweak hierarchy problem which posits copies of the Standard Model with varying Higgs mass-squared parameters. Reheating proceed…
Addressing Local Realism through Bell Tests at Colliders
Matthew Low
One of the most notable aspects of quantum systems is that their components can exhibit correlations much stronger than those allowed by classical physics. Two examples of quantum…
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…
