Using Symmetries to Improve Quantum de Finetti Reductions

The analysis of quantum information processing protocols for generic states is challenging. In contrast, when the states are IID, i.e. the same in every round of the protocol, the analysis greatly simplifies. de Finetti reductions are important to reduce the analysis of quantum information processing tasks to the IID case, though this reduction has some cost associated with it. In this talk I will describe how IID-symmetries can be used to reduce the cost associated with the quantum de Finetti reductions.
