Spin entanglement signatures of proton from a light-front Hamiltonian
Chen Qian, Siqi Xu, Yang-Guang Yang +1
Quantum entanglement provides a quantitative probe of the internal structure of hadrons and offers a sensitive means to study the quantum correlation in the hadron wave functions.…

Quantum steering and discord in hyperon-antihyperon system in electron-positron annihilation
Sihao Wu, Chen Qian, Qun Wang +1
Hyperon-antihyperon pairs produced in high-energy electron-positron annihilation are promising systems for the study of quantum information properties. In this work, we make an ana…

Quark and gluon entanglement in the proton based on a light-front Hamiltonian
Chen Qian, Siqi Xu, Yang-Guang Yang +1
Given that the wave function of a proton can be derived relativistically and nonperturbatively from a light-front quantized Hamiltonian, investigating the quantum correlation betwe…
