Entanglement entropy is a measure of quantum entanglement. In recent years, this quantity has been found to be useful in probing (theoretically) the nature of quantum many-particle states, in particular non-local and global properties. I will first give a survey of theoretical results on entanglement entropies in various classes of many-body quantum states. I will then describe our own results on the entanglement entropy in the fractional quantum hall states of the Laughlin sequence. We have found that suitably defined entanglement entropies access the topological nature and exclusion statistics inherent in fractional quantum Hall states.
