    "abstract": "A complete analysis on the generation of spin entanglement from NRQED is\npresented. The results of entanglement are obtained with relativistic\ncorrection to the leading order of (v/c)^2. It is shown that to this order the\ndegree of entanglement of a singlet state does not change under time evolution\nwhereas the triplet state can change.",
