Information-Disturbance Tradeoff in Quantum State Discrimination
Francesco Buscemi, Massimiliano F. Sacchi
When discriminating between two pure quantum states, there exists a quantitative tradeoff between the information retrieved by the measurement and the disturbance caused on the unk…
Quantum erasure of decoherence
F. Buscemi, G. Chiribella, G. M. D'Ariano
We consider the classical algebra of observables that are diagonal in a given orthonormal basis, and define a complete decoherence process as a completely positive map that asympto…
Channel correction via quantum erasure
Francesco Buscemi
By exploiting a generalization of recent results on environment-assisted channel correction, we show that, whenever a quantum system undergoes a channel realized as an interaction…
A minimum-disturbing quantum state discriminator
Francesco Buscemi, Massimiliano F. Sacchi
We propose two experimental schemes for quantum state discrimination that achieve the optimal tradeoff between the probability of correct identification and the disturbance on the…
On the minimum number of unitaries needed to describe a random-unitary channel
Francesco Buscemi
We provide, in an extremely simple way, an upper bound to the minimum number of unitary operators describing a general random-unitary channel.
Superbroadcasting and classical information
G. Chiribella, G. M. D'Ariano, C. Macchiavello +2
We address the problem of broadcasting N copies of a generic qubit state to M>N copies by estimating its direction and preparing a suitable output state according to the outcome of…
