    "abstract": "We study the dynamics of momentum entanglement generated in the lowest-order\nQED interaction between two massive spin-1/2 charged particles, which grows in\ntime as the two fermions exchange virtual photons. We observe that the degree\nof generated entanglement between interacting particles with initial\nwell-defined momentum can be infinite. We explain this divergence in the\ncontext of entanglement theory for continuous variables, and show how to\ncircumvent this apparent paradox. Finally, we discuss two different\npossibilities of transforming momentum into spin entanglement, through\ndynamical operations or through Lorentz boosts.",
