    "abstract": "This paper attempts to give an overview about sufficiency in the setting of\nquantum statistics. The basic concepts are treated paralelly to the the measure\ntheoretic case. It turns out that several classical examples and results have a\nnon-commutative analogue. Some of the results are presented without proof (but\nwith exact references) and the presentation is intended to be self-contained.\nThe main examples discussed in the paper are related the Weyl algebra and to\nthe exponential family of states. The characterization of sufficiency in terms\nof quantum Fisher information is a new result.",
