    "abstract": "We show the decrease of spin-spin entanglement between two s=1/2 fermions or\ntwo photons due to local transfer of correlations from the spin to the momentum\ndegree of freedom of one of the two particles. We explicitly show how this\nphenomenon operates in the case where one of the two fermions (photons) passes\nthrough a local homogeneous magnetic field (optically-active medium), losing\nits spin correlations with the other particle.",
