    "abstract": "The problem of dipole-dipole decoherence of nuclear spins is considered for\nstrongly entangled spin cluster. Our results show that its dynamics can be\ndescribed as the decoherence due to interaction with a composite bath\nconsisting of fully correlated and uncorrelated parts. The correlated term\ncauses the slower decay of coherence at larger times. The decoherence rate\nscales up as a square root of the number of spins giving the linear scaling of\nthe resulting error. Our theory is consistent with recent experiment reported\nin decoherence of correlated spin clusters.",
