Hardware-efficient quantum simulation of intense-field QED
Zhuoyi Li, Bin Xu, Zhongtian Dong +4
Strong electromagnetic backgrounds make quantum electrodynamics a real-time nonperturbative problem involving dressed fermions and dynamical photons. We propose a trapped-ion proto…
Quantum Sensing Radiative Decays of Neutrinos and Dark Matter Particles
Zhongtian Dong, Doojin Kim, Kyoungchul Kong +2
We explore a novel strategy for detecting the radiative decay of very weakly interacting particles by leveraging the extreme sensitivity of quantum devices, such as superconducting…
Hybrid quantum-classical approach for combinatorial problems at hadron colliders
Jacob L. Scott, Zhongtian Dong, Taejoon Kim +6
In recent years, quantum computing has drawn significant interest within the field of high-energy physics. We explore the potential of quantum algorithms to resolve the combinatori…
Probing the CP Structure of the Top Quark Yukawa at the Future Muon Collider
Morgan E. Cassidy, Zhongtian Dong, Kyoungchul Kong +3
We study the top-Higgs coupling with a CP violating phase at a future multi-TeV muon collider. We focus on processes that are directly sensitive to the top quark Yukawa coupli…
Analytical Insights on Hadronic Top Quark Polarimetry
Zhongtian Dong, Dorival Gonçalves, Kyoungchul Kong +2
Top quark polarization provides an important tool for studying its production mechanisms, spin correlations, top quark properties, and new physics searches. Unlike lighter quarks,…
When the Machine Chimes the Bell: Entanglement and Bell Inequalities with Boosted
Zhongtian Dong, Dorival Gonçalves, Kyoungchul Kong +1
The Large Hadron Collider provides a unique opportunity to study quantum entanglement and violation of Bell inequalities at the highest energy available today. In this paper, we wi…
