Dynamical redistribution of quantum resources in tree-level Bhabha scattering
Zan Cao, Meng-Long Song, Xue-Ke Song +2
The fundamental interactions governed by quantum electrodynamics (QED) are intrinsically rich in quantum resources, yet how these resources dynamically redistribute during relativi…

Genuine tripartite entanglement in Bhabha scattering with an entangled spectator particle
Zan Cao, Meng-Long Song, Xue-Ke Song +2
From the perspective of quantum information science, we investigate tree-level Bhabha scattering between an incident electron and a positron , where is initially entangl…

Quantum steering as a probe of energy transfer in quantum batteries
Meng-Long Song, Zan Cao, Xue-Ke Song +2
This study investigates the role of EPR steering in characterizing the energy dynamics of quantum batteries (QBs) within \textcolor{black}{a charging system that features shared re…
