Intrinsic metrological resolution as a distance measure and nonclassical light
Rivas, A.; Luis, A. (2008)We elaborate on a Hilbert-Schmidt distance measure assessing the intrinsic metrological accuracy in the detection of signals imprinted on quantum probe states by signal-dependent transformations. For small signals this ... -
Nonclassicality of states and measurements by breaking classical bounds on statistics
Rivas, A.; Luis, A. (2009)We derive exceedingly simple practical procedures revealing the quantum nature of states and measurements by the violation of classical upper bounds on the statistics of arbitrary measurements. Data analysis is minimum, ... -
Practical schemes for the measurement of angular-momentum covariance matrices in quantum optics
Rivas, A.; Luis, A. (2008)We develop practical schemes for the measurement of the covariance matrix for intrinsic angular-momentum variables in quantum optics. We particularize this approach to two-beam polarimetry and interferometry, as well as ...
