摘要：

The photon-added entangled coherent state is introduced. The influence on the photon statistics is studied via photon adding in some mode of entangled coherent states. Because of the entanglement between the modes of the field, photon adding in mode a not only results in the increase of the mean number of mode a, but also changes the mean number of mode b ( increasing of decreasing). It is shown that the fields have remarkable sub-poissonian photon statistics and the squeezing after adding photons.
