Joint estimation of real squeezing and displacement
G. Chiribella, G. M. D'Ariano, M. F. Sacchi
We study the problem of joint estimation of real squeezing and amplitude of the radiation field, deriving the measurement that maximizes the probability density of detecting the tr…
Informationally complete measurements on bipartite quantum systems: comparing local with global measurements
G. M. D'Ariano, P. Perinotti, M. F. Sacchi
Informationally complete measurements allow the estimation of expectation values of any operator on a quantum system, by changing only the data-processing of the measurement outcom…
Minimax discrimination of two Pauli channels
G. Mauro D'Ariano, Massimiliano F. Sacchi, Jonas Kahn
We consider the problem of optimally discriminating two Pauli channels in the minimax strategy, maximizing the smallest of the probabilities of correct identification of the channe…
Minimum error discrimination of Pauli channels
Massimiliano F. Sacchi
We solve the problem of discriminating with minimum error probability two given Pauli channels. We show that, differently from the case of discrimination between unitary transforma…
Optimal estimation of group transformations using entanglement
G. Chiribella, G. M. D'Ariano, M. F. Sacchi
We derive the optimal input states and the optimal quantum measurements for estimating the unitary action of a given symmetry group, showing how the optimal performance is obtained…
Optimal discrimination of quantum operations
Massimiliano F. Sacchi
We address the problem of discriminating with minimal error probability two given quantum operations. We show that the use of entangled input states generally improves the discrimi…
