Entanglement theory and communication
Graph states as a versatile tool to capture entanglement properties
Entanglement is a resource in quantum information theory and plays a key role in the understanding of interacting quantum many-body systems. We are concerned with various aspects of entanglement theory as the theory of quantitatively assessing quantum correlations. We also think about using such ideas in the development of quantum communication protocols, guided by the vision of a quantum internet.
