Query: Soft-Photons and the entanglement of charged qubtis   In this work, I consider the effect of the unavoidable presence of
soft-photons on the spin entanglement of charged qubits, arguing that the spin
entanglement is not modified if we consider the effects of the infrared
structure of QED on it.
