Abstract
We present a scheme for creating quantum entangled atomic states through th e coherent spin-exchange collision of a spinor Bose-Einstein condensate. Th e state generated possesses macroscopic Einstein-Podolsky-Rosen correlation and the fluctuation in one of its quasispin components vanishes. We show t hat an elongated condensate with large aspect ratio is most suitable for cr eating such a state.
