    "abstract": "We study how two magnetic impurities embedded in a solid can be entangled by\nan injected electron scattering between them and by subsequent measurement of\nthe electron\u0027s state. We start by investigating an ideal case where only the\nelectronic spin interacts successively through the same unitary operation with\nthe spins of the two impurities. In this case, high (but not maximal)\nentanglement can be generated with a significant success probability. We then\nconsider a more realistic description which includes both the forward and back\nscattering amplitudes. In this scenario, we obtain the entanglement between the\nimpurities as a function of the interaction strength of the electron-impurity\ncoupling. We find that our scheme allows us to entangle the impurities\nmaximally with a significant probability.",
