摘要：

We have observed two-photon quantum interference in a Michelson interferometer. For the first time, we experimentally demonstrated two-photon quantum interference patterns, which show the transition from nonsubwavelength interference fringes to the general subwavelength interference. At the same time, a photon bunching effect was also shown by a postselection. The vertical bar 1, 1 > state with a single photon in a mode corresponding to each arm of the interferometer was exclusively postselected by using path difference between two arms.
