Abstract: We find the allowed complex overlaps for N equidistant pure quantum states. The accessible overlaps define a petal-shaped area on the Argand plane. Each point inside the petal represents a set of N linearly independent pure states and each point on its contour represents a set of N linearly dependent pure states. We find the optimal probabilities of success of discriminating unambiguously in which of the N equidistant states the system is. We show that the phase of the involved overlap plays an important role in the probability of success. For a fixed overlap modulus, the success probability is highest for the set of states with an overlap with phase equal to zero. In this case, if the process fails, then the information about the prepared state is lost. For states with a phase different from zero, the information could be obtained with an error-minimizing measurement protocol.

This review undertakes an assessment of CCT programs and the conventional theory that has evolved to justify them. It concludes that successes to date are limited, with positive effects on schooling and some aspects of health and nutrition in poor households, but weak effects on alleviating poverty in the short term and uncertain effects on educational aspects of human capital formation and poverty reduction in the long term. In a broader and more comprehensive view of social policy, as opposed to a minimalist focus, the key issue is how to integrate CCT programs with other social programs to overcome traditional patterns of segmentation in Latin America and thereby cultivate citizenship.
