Channel Steering
Marco Piani
We introduce and study the notion of steerability for channels. This generalizes the notion of steerability of bipartite quantum states. We discuss a key conceptual difference betw…
Einstein-Podolsky-Rosen steering provides the advantage in entanglement-assisted subchannel discrimination with one-way measurements
Marco Piani, John Watrous
Steering is the entanglement-based quantum effect that embodies the "spooky action at a distance" disliked by Einstein and scrutinized by Einstein, Podolsky, and Rosen. Here we pro…
Quantumness of correlations, quantumness of ensembles and quantum data hiding
Marco Piani, Varun Narasimhachar, John Calsamiglia
We study the quantumness of correlations for ensembles of bi- and multi-partite systems and relate it to the task of quantum data hiding. Quantumness is here intended in the sense…
Quantifying non-classical and beyond-quantum correlations in the unified operator formalism
J. Geller, M. Piani
Acin et al. introduced a unified framework for the study of no-signalling correlations. Such a framework is based on the notion of local quantum measurements, but, in order to acco…
