We investigate the correlations that can arise between Alice and Bob in prepare-and-measure communication scenarios where source (Alice) measurement device (Bob) share prior entanglement. The paradigmatic example of such a scenario is quantum dense-coding protocol, capacity qudit be doubled if two-qudit entangled state shared Bob. provide examples actually require more general protocols based o...

In order to determine the predictive validity of the premarital inventory PREPARE, this study assessed the utility of PREPARE in predicting marital success. A 3-year follow-up study was conducted with 164 couples who took PREPARE during their engagement. As hypothesized, it was found that satisfied couples scored significantly higher on the inventory than dissatisfied couples, divorced couples,...

This study clearly replicated the previous findings which demonstrated the predictive validity of PREPARE. Like the previous study, this longitudinal study was a 3-year follow-up of 179 couples who took PREPARE during their engagement. As in the initial longitudinal study, PREPARE predicted, with about 80% accuracy, couples who got divorced from those that were happily married. Also, the same l...
