    "abstract": "Universal two-particle entanglement processes are analyzed in arbitrary\ndimensional Hilbert spaces. On the basis of this analysis the class of possible\noptimal universal entanglement processes is determined whose resulting output\nstates do not contain any separable states. It is shown that these processes\nform a one-parameter family. For all Hilbert space dimensions larger than two\nthe resulting optimally entangled output states are mixtures of anti-symmetric\nstates which are freely entangled and which also preserve information about\ninput states. Within this one-parameter family there is only one process by\nwhich all information about any input state is destroyed completely.",
