Heralded Entanglement of Arbitrary Degree in Remote Qubits

Incoherent scattering of photons off two remote atoms with a Lambda-level structure is used as a basic Young-type interferometer to herald long-lived entanglement of an arbitrary degree. The degree of entanglement, as measured by the concurrence, is found to be tunable by two easily accessible experimental parameters. Fixing one of them to certain values unveils an analog to the Malus' law. An estimate of the variation in the degree of entanglement due to uncertainties in an experimental realization is given.Comment: published version, 4 pages and 2 figure

Time, Judgment, and Competitive Spirituality: A Reading of the Development of the Doctrine of Purgatory

Why has purgatory virtually disappeared front Catholic belief and practice since Vatican II? A competitive spirituality, gravitating around the religious vocation of ascetics from the late Middle Ages, enabled the doctrine by extending the temporal horizon within which God\u27s favorable judgment could be secured, first, in the lifelong practice of ascetics in their spiritual competition with martyrs, and then into a supernatural time required for laypersons and ascetics who could not meet the standard set by saintly ascetics. The loss of this competitive spirituality after Vatican II led to the loss of belief in purgatory and devotional practice surrounding it

The Analogy of Tradition: Method and Theological Judgment

The author examines a basic question for theological inquiry: how is congruence between past and present meaning achieved in tradition and in theological judgment? He begins by criticizing the account of traditional continuity offered in the recent work of Kathryn Tanner and by considering the limits of correlation in explaining congruence in theological judgment. Constructively, he proposes an understanding of method as a pragmatics of tradition in which a certain use of analogy accounts for traditional and theological congruence

For What May We Hope? Thoughts on the Eschatological Imagination

After reflecting on the reluctance of modem theology to engage in eschatological speculation, the author argues that plenty of traditional Catholic beliefs warrant a rich exercise of the eschatological imagination. The life of the blessed dead provides a test case for such speculation, with Jesus\u27 own resurrected life in the Gospels invoked as an interpretive measure for the resurrected life of believers
