Optimization of quantum universal detectors
G. M. D'Ariano, P. Perinotti, M. F. Sacchi
The expectation value <O> of an arbitrary operator O can be obtained via a universal measuring apparatus that is independent of O, by changing only the data-processing of the outco…
LOCC protocols for entanglement transformations
G. M. D'Ariano, M. F. Sacchi
We construct the protocols to achieve probabilistic and deterministic entanglement transformations for bipartite pure states by means of local operations and classical communicatio…
Optimal local discrimination of two multipartite pure states
S. Virmani, M. F. Sacchi, M. B. Plenio +1
In a recent paper, Walgate et. al. demonstrated that any two orthogonal multipartite pure states can be optimally distinguished using only local operations. We utilise their result…
Homodyne characterization of active optical media
G. M. D'Ariano, M. G. A. Paris, M. F. Sacchi
An effective maximum likelihood method is suggested to characterize the absorption/amplification properties of active optical media through homodyne detection.
Quantum cloning optimal for joint measurements
G. M. D'Ariano, M. F. Sacchi
We show that universally covariant cloning is not optimal for achieving joint measurements of noncommuting observables with minimum added noise. For such a purpose a cloning transf…
Feedback-assisted measurement of the free mass position under the Standard Quantum Limit
G. M. D'Ariano, M. F. Sacchi, R. Seno
The Standard Quantum Limit (SQL) for the measurement of a free mass position is illustrated, along with two necessary conditions for breaching it. A measurement scheme that overcom…
