Symmetries in quantum networks lead to no-go theorems for entanglement distribution and to verification techniques
Abstract Quantum networks are promising tools for the implementation of long-range quantum communication. The characterization of quantum correlations in networks and their usefulness for information processing is therefore central for the progress of the field, but so far only results for small basic network structures or pure quantum states are …
