    "abstract": "We study entanglement in the scattering processes by fixed impurity and Kondo\nimpurity. The fixed impurity plays a role as spin state filter that is employed\nto concentrate entanglement between the scattering particle and the\nunscattering particle. One Kondo impurity can entangle two noninteracting\nscattering particles while one scattering particle can entangle two separate\nnoninteracting Kondo impurities.",
