Optimal superbroadcasting of mixed qubit states
Francesco Buscemi, Giacomo Mauro D'Ariano, Chiara Macchiavello +1
"Broadcasting", namely distributing information over many users, suffers in-principle limitations when the information is quantum. This poses a critical issue in quantum informatio…
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…
Optimal Time-Reversal of Multi-phase Equatorial States
Francesco Buscemi, Giacomo Mauro D'Ariano, Chiara Macchiavello
Even though the time-reversal is unphysical (it corresponds to the complex conjugation of the density matrix), for some restricted set of states it can be achieved unitarily, typic…
