Experimental characterization of quantum processes: a selective and efficient method in arbitrary finite dimension
Quimey Pears Stefano, Ignacio Perito, Juan José Miguel Varga +2
The temporal evolution of a quantum system can be characterized by quantum process tomography, a complex task that consumes a number of physical resources scaling exponentially wit…
Characterization of non-signaling correlations from mutual information
Ignacio Perito, Guido Bellomo, Daniel Galicer +3
We present a characterization of the set of non-signaling correlations in terms of a two dimensional representation that involves the maximal value of a Bell functional and the mut…
Impossibility of memory in hidden-signaling models for quantum correlations
Ignacio Perito, Guido Bellomo, Daniel Galicer +3
We consider a toy model for non-local quantum correlations in which nature resorts to some form of hidden signaling (i.e., signaling between boxes but not available to the users) t…
Selective and Efficient Quantum Process Tomography in Arbitrary Finite Dimension
Ignacio Perito, Augusto Roncaglia, Ariel Bendersky
The characterization of quantum processes is a key tool in quantum information processing tasks for several reasons: on one hand, it allows to acknowledge errors in the implementat…
