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…
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…
Information-disturbance tradeoff for spin coherent state estimation
Massimiliano F. Sacchi
We show how to quantify the optimal tradeoff between the amount of information retrieved by a quantum measurement in estimating an unknown spin coherent state and the disturbance o…
Superbroadcasting of harmonic oscillators mixed states
G. M. D'Ariano, P. Perinotti, M. F. Sacchi
We consider the problem of broadcasting quantum information encoded in the displacement parameter for an harmonic oscillator, from N to M>N copies of a thermal state. We show the W…
Information-disturbance tradeoff in estimating a maximally entangled state
Massimiliano F. Sacchi
We derive the amount of information retrieved by a quantum measurement in estimating an unknown maximally entangled state, along with the pertaining disturbance on the state itself…
Superbroadcasting of conjugate quantum variables
Giacomo M. D'Ariano, Paolo Perinotti, Massimiliano F. Sacchi
We consider the problem of broadcasting arbitrary states of radiation modes from N to M>N copies by a map that preserves the average value of the field and optimally reduces the to…
