Entanglement can be considered the key resource behind many applications of quantum information processing, as well as critical for the foundation of thermodynamics and the emergence of a classical world. While the simplest applications can be sufficiently addressed with the, now relatively well understood, entanglement of two qubits, more complex notions of entanglement hold huge potential...
This talk focuses on the relationship between the correlations we can measure between quantum objects, and the entanglement shared by them. In particular, we show how these correlations can be used to quantify (not just qualify) both bipartite and genuine multipartite entanglement, and show how the uncertainty principle fundamentally alters the relationship between correlation and entanglement...
Experimentally quantifying entanglement is highly desired for applications of quantum simulation experiments to fundamental questions, e.g., in quantum statistical mechanics and condensed-matter physics. At the same time it poses a significant challenge because the evaluation of entanglement measures typically requires the full reconstruction of the quantum state, which is extremely costly in...
