Clean Positive Operator Valued Measures
F. Buscemi, G. M. D'Ariano, M. Keyl +2
In quantum mechanics the statistics of the outcomes of a measuring apparatus is described by a positive operator valued measure (POVM). A quantum channel transforms POVM's into POV…
Inverting quantum decoherence by classical feedback from the environment
Francesco Buscemi, Giulio Chiribella, Giacomo Mauro D'Ariano
We show that for qubits and qutrits it is always possible to perfectly recover quantum coherence by performing a measurement only on the environment, whereas for dimension d>3 ther…
Economical Phase-Covariant Cloning of Qudits
Francesco Buscemi, Giacomo Mauro D'Ariano, Chiara Macchiavello
We derive the optimal N to M phase-covariant quantum cloning for equatorial states in dimension d with M=kd+N, k integer. The cloning maps are optimal for both global and single-qu…
