    "abstract": "The stability of two entangled spins dressed by electrons is studied by\ncalculating the scattering phase shifts. The interaction between electrons is\ninterpreted by fully relativistic QED and the screening effect is described\nphenomenologically in the Debye exponential form $e^{-\\alpha r}$. Our results\nshow that if the (Einstein-Podolsky-Rosen-) EPR-type states are kept stable\nunder the interaction of QED, the spatial wave function must be\nparity-dependent. The spin-singlet state $s=0$ and the polarized state $\\frac\n1{\\sqrt{2}}(\\mid +-\u003e -\\mid -+\u003e)$ along the z-axis\\QTR{bf}{\\}give rise to two\ndifferent kinds of phase shifts\\QTR{bf}{.} Interestingly, the interaction\nbetween electrons in the spin-singlet pair is found to be attractive. Such an\nattraction could be very useful when we extract the entangled spins from\nsuperconductors. A mechanism to filter the entangled spins is also discussed.",
