论文摘要
我们报告了一项系统的研究，该研究涉及量子电动力学两粒子散射过程中树级生成的螺旋性自由度之间的纠缠。我们确定了将传出颗粒彼此纠缠的必要和充分的动力条件，并通过Bhabha和Compton散射暴露了迄今未知一代最大或几乎最大的纠缠。根据量子信息理论，我们的工作是重新审视量子场理论和高能物理学的早期一步。
We report on a systematic study on the entanglement between helicity degrees of freedom generated at tree-level in quantum electrodynamics two-particle scattering processes. We determine the necessary and sufficient dynamical conditions for outgoing particles to be entangled with one another, and expose the hitherto unknown generation of maximal or nearly maximal entanglement through Bhabha and Compton scattering. Our work is an early step in revisiting quantum field theory and high-energy physics in the light of quantum information theory.
