    "abstract": "The position variance of a single-mode Yuen states can go below the standard\nquantum limit. For two-mode squeezed states, it is shown that the\ntime-dependent evolution of the entanglement of formation can be contractive,\ngoing below that of the squeezed state with minimum Einstein-Podolsky-Rosen\ndispersions, and increasing thereafter. The rate of change of the\nEinstein-Podolsky-Rosen dispersions as a function of the two-mode phases\ncontrol this process. Contractive entanglement is shown to be equivalent to a\nrotating phase space accompanied by time-dependent single-mode squeezing.",
