We study the possibilities and the limits of quantum information processing in different scenarios and for different tasks.
E.g.: channel discrimination with entanglement and local measurements coordinated by classical communication  (relevant for quantum metrology )
We study different aspects of quantum information processing including new computational paradigms, the role of measurement in transforming information, and how we can make more precise measurements. Click on the following links to see more.
