    "abstract": "We present a scheme for demonstrating violation of Bell\u0027s inequalities using\na spin-1/2 system entangled with a pair of classically distinguishable wave\npackets in a harmonic potential. In the optical domain, such wave packets can\nbe represented by coherent states of a single light mode. The proposed scheme\ninvolves standard spin-1/2 projections and measurements of the position and the\nmomentum of the harmonic oscillator system, which for a light mode can be\nrealized by means of homodyne detection. We discuss effects of imperfections,\nincluding non-unit efficiency of the homodyne detector, and point out a close\nlink between the visibility of interference and violation of Bell\u0027s\ninequalities in the described scheme.",
