摘要：

The investigation of photon statistics and quadrature squeezing in superpositions of two coherent states under the influence of a continuous measurement of photon number shows that the photon statistics of the cavity mode oscillates between sub-Poissonian and super-Poissonian distributions and that the quadrature fluctuation oscillates between squeezing and nonsqueezing at each time when one photon of a cavity mode is registered by a counter. These oscillatory behaviors are caused by the influence of the continuous measurement of photon number and the quantum interference between the two coherent states in the superposition. © 1995 The American Physical Society.
