    "abstract": "We investigate the effect of a spin bath on the spin transfer functions of a\npermanently coupled spin system. When each spin is coupled to a seperate\nenvironment, the effect on the transfer functions in the first excitation\nsector is amazingly simple: the group velocity is slowed down by a factor of\ntwo, and the fidelity is destabilized by a modulation of |cos Gt|, where G is\nthe mean square coupling to the environment.",
