We study relativistic entanglement of a bipartite system consisting of massive spin-1/2 particles with momenta. The spin state is described by the maximally entangled Bell state and momenta are given by entangled Gaussian distributions. We conceptualize the dependency between spin and momentum in relativity along the lines of controlled operations in quantum information theory. This leads to a systematic study of maps generated by Wigner rotations on the spin degree of freedom of the total system in different boost scenarios. We use a visualization tool from quantum information theory in order to get better insight into how and why the entanglement changes in different boost geometries.

纠缠动量生成的地图:探索相对论中的自旋纠缠

我们研究了由具有动量的大量自旋 1/2 粒子组成的二分系统的相对论纠缠。自旋状态由最大纠缠的贝尔状态描述,动量由纠缠的高斯分布给出。我们根据量子信息论中的受控操作概念化了相对论中自旋和动量之间的依赖关系。这导致对 Wigner 旋转生成的地图在不同助推场景下整个系统的自旋自由度的系统研究。我们使用来自量子信息理论的可视化工具,以便更好地了解纠缠在不同的助推几何形状中如何以及为何发生变化。
