Optimal covariant quantum networks
G. Chiribella, G. M. D'Ariano, P. Perinotti
A sequential network of quantum operations is efficiently described by its quantum comb, a non-negative operator with suitable normalization constraints. Here we analyze the case o…
The Quantum No-Stretching: A geometrical interpretation of the no-cloning theorem
Giacomo Mauro D'Ariano, Paolo Perinotti
We consider the ideal situation in which a space rotation is transferred from a quantum spin j to a quantum spin l different from j. Quantum-information theoretical considerations…
Realization schemes for quantum instruments in finite dimensions
Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti
We present a general dilation scheme for quantum instruments with continuous outcome space in finite dimensions, in terms of an indirect POVM measurement performed on a finite dime…
Barycentric decomposition of quantum measurements in finite dimensions
G. Chiribella, G. M. D'Ariano, D. M. Schlingemann
We analyze the convex structure of the set of positive operator valued measures (POVMs) representing quantum measurements on a given finite dimensional quantum system, with outcome…
Adaptive Bayesian and frequentist data processing for quantum tomography
G. M. D'Ariano, D. F. Magnani, P. Perinotti
The outcome statistics of an informationally complete quantum measurement for a system in a given state can be used to evaluate the ensemble expectation of any linear operator in t…
Optimal quantum tomography for states, measurements, and transformations
A. Bisio, G. Chiribella, G. M. D'Ariano +2
We present the first complete optimization of quantum tomography, for states, POVMs, and various classes of transformations, for arbitrary prior ensemble and arbitrary representati…
