About the use of entanglement in the optical implementation of quantum information processing
M. G. A. Paris, G. M. D'Ariano, P. Lo Presti +1
We review some applications of entanglement to improve quantum measurements and communication, with the main focus on the optical implementation of quantum information processing.…
Improved discrimination of unitaries by entangled probes
G. Mauro D'Ariano, Paoloplacido Lo Presti, Matteo G. A. Paris
We consider the problem of discriminating among a set of unitaries by means of measurements performed on the state undergoing the transformation. We show that use of entangled prob…
Using entanglement improves precision of quantum measurements
G. Mauro D'Ariano, Paoloplacido Lo Presti, Matteo G. A. Paris
We show how entanglement can be used to improve the estimation of an unknown transformation. Using entanglement is always of benefit, in improving either the precision or the stabi…
Maximum-likelihood method in quantum estimation
M. G. A. Paris, G. M. D'Ariano, M. F. Sacchi
The maximum-likelihood method for quantum estimation is reviewed and applied to the reconstruction of density matrix of spin and radiation as well as to the determination of severa…
Quorum of observables for universal quantum estimation
G. Mauro D'Ariano, Lorenzo Maccone, Matteo G. A. Paris
Any method for estimating the ensemble average of arbitrary operator (observables or not, including the density matrix) relates the quantity of interest to a complete set of observ…
Orthogonality relations in Quantum Tomography
G. M. D'Ariano, L. Maccone, M. G. A. Paris
Quantum estimation of the operators of a system is investigated by analyzing its Liouville space of operators. In this way it is possible to easily derive some general characteriza…
