Query: Multivariate Discrimination in Quantum Target Detection   We describe a simple multivariate technique of likelihood ratios for improved
discrimination of signal and background in multi-dimensional quantum target
detection. The technique combines two independent variables, time difference
and summed energy, of a photon pair from the spontaneous parametric
down-conversion source into an optimal discriminant. The discriminant
performance was studied in experimental data and in Monte-Carlo modelling with
clear improvement shown compared to previous techniques. As novel detectors
become available, we expect this type of multivariate analysis to become
increasingly important in multi-dimensional quantum optics.
