摘要
We show the feasibility of a tomographic reconstruction of "Schrodinger-cat states" generated according to the scheme proposed by S. Song, C.M. Caves, and TT. Yurke [Phys. Rev. A 41, 5261 (1990)]. We present a technique that tolerates realistic values for quantum efficiency at photodetectors. The measurement can be achieved by a standard experimental setup. [S1050-2947(99)05603-6].
