Operational characterization of quantum properties

Marco Piani, University of Strathclyde

 Quantum features like quantum superposition and quantum correlations — the latter comprising, but not limited to entanglement — are both of foundational and applicative interest. We develop tools to characterize such features operationally, looking for ways to detect, quantify, and utilize them. Some recent results I will report on regard the use of such features in the discrimination of physical processes, a task within the area of quantum metrology. Given that strong quantum features lead to a better metrological performance, it is possible to use such performance to certify the quantum features in a semi-device independent way, which relaxes some of the assumptions about the potential experimental implementation.
