    "abstract": "There are fundamental limits to the accuracy with which one can determine the\nstate of a quantum system. I give an overview of the main approaches to quantum\nstate discrimination. Several strategies exist. In quantum hypothesis testing,\na quantum system is prepared in a member of a known, finite set of states, and\nthe aim is to guess which one with the minimum probability of error. Error free\ndiscrimination is also sometimes possible, if we allow for the possibility of\nobtaining inconclusive results. If no prior information about the state is\nprovided, then it is impractical to try to determine it exactly, and it must be\nestimated instead. In addition to reviewing these various strategies, I\ndescribe connections between state discrimination, the manipulation of quantum\nentanglement, and quantum cloning. Recent experimental work is also discussed.",
