Description

The concept of entanglement is a negative: the non-factorizable states are called entangled. Furthermore, measures of entanglement are required to be monotonic under classes of operations including LOCC (=local operations and classical communication). Hence, the properties of entanglement are really just the reflection of the structure of the class LOCC of cptp maps. In this project we want to understand this class better, along various lines of asking about the power of LOCC to perform certain information theoretic or statistical tasks.
