18. For a single-mode cavity field, the reconstruction of the Wigner function is studied using the similar scheme as discussed in this paper by L. G. Lutterbach and L. Davidovich, Phys. Rev. Lett. 78, 2547 (1997).
19. The interaction time is subject to thermal noise with a normalized standard deviation 5% [M. S. Kim, G. Antesberger, C. T. Bodendorf, and H. Walther, Phys. Rev. A 58, R65 (1998)].
20. We checked the mean-field approximation as we calculated the exact value of Eq. (22) for the nonlocal state (1). The result in Eq. (26) is within 0.1% of the exact algebraic calculation, which implies that the correlation effect between Π̂ and Δ (n̂) is negligible for fields of small amplitudes. We conjecture that the mean-field approximation holds for the displaced nonlocal fields of the displacements |α| < 1 and |β|< 1.
