    Continuous-variable teleportation in the characteristic-function description

    Full text link
    We give a description of the continuous-variable teleportation protocol in terms of the characteristic functions of the quantum states involved. The Braunstein--Kimble protocol is written for an unbalanced homodyne measurement and arbitrary input and resource states. We show that the output of the protocol is a superposition between the input one-mode field and a classical one induced by measurement and classical communication. We choose to describe the input state distortion through teleportation by the average photon number of the measurement-induced field. Only in the case of symmetric resource states we find a relation between the optimal added noise and the minimal EPR correlations used to define inseparability.Comment: 12 page

    Eroticism and Justice: Harold Pinter’s Screenplay of Ian McEwan’s The Comfort of Strangers

    Get PDF
    The article centres upon Pinter’s creative adaptation of McEwan’s deeply allusive and disquieting text probing, amongst others, the intricacies and tensions of gender relations and sexual intimacy. It examines the screenplay-regarded by many critics as not merely an adaptation of the novel but another, very powerful work of art-addressing Pinter’s method as an adapter and highlighting the artist’s imaginative attempts at fostering a better appreciation of the connections between authoritarian impulses, love and justice. Similarly to a number of other Pinter filmscripts and plays of the 1980s and 1990s, the erotic and the lethal alarmingly intersect in this screenplay where the ostensibly innocent-an unmarried English couple on a holiday in Venice, who are manipulated, victimized and, ultimately, destroyed-are subtly depicted as partly complicit in their own fates

    The Limits of Language as the Limits of the World: Cormac McCarthy’s and David Markson’s Post-Apocalyptic Novels

    The article examines the correlation between the world and the word in two novels which engage with a post-apocalyptic scenario: David Markson’s Wittgenstein’s Mistress (1988) and Cormac McCarthy’s The Road (2006). Shifting the focus from the very event of catastrophe to the notion of survival through memory and storytelling, both novels problematize the strained relationship between language and reality in an increasingly diminished and dehumanized world. My aim is to investigate the limits of language as well as its capacity to withstand the chaos, loss, trauma, and death that follow the apocalypse. The issues to be considered include the influence of external experience on forms of communication, the role of central metaphors (the archive and the museum in Markson’s novel; cinders and the road in McCarthy’s) and their relation to the form of both novels, as well as the word’s (in)capacity to preserve human values and hopes. Both novels will be discussed as deconstructionist projects in which language becomes a habitat at once impossible and life-preserving: in Wittgenstein’s Mistress it plays the role of both home and prison, whereas in The Road it functions as messianic discourse which simultaneously carries, propels and extinguishes the human hope for a transcendental reality beyond the post-apocalyptic emptiness and doubt

    Know How and Acts of Faith

    My topic in this paper is the nature of faith. Much of the discussion concerning the nature of faith proceeds by focussing on the relationship between faith and belief. In this paper, I explore a different approach. I suggest that we approach the question of what faith involves by focussing on the relationship between faith and action. When we have faith, we generally manifest it in how we act; we perform acts of faith: we share our secrets, rely on other’s judgment, refrain from going through our partner’s emails, let our children prepare for an important exam without our interference. Religious faith, too is manifested in acts of faith: attending worship, singing the liturgy, fasting, embarking on a pilgrimage. I argue that approaching faith by way of acts of faith, reveals that faith is a complex mental state whose elements go beyond doxastic states towards particular propositions. It also involves conative states and – perhaps more surprisingly – know how. This has consequences for the epistemology of faith: the role of testimony and experts, the importance of practices, and what we should make of Pascal’s advice for how to acquire faith

    Behavior-Based Early Language Development on a Humanoid Robot

    Get PDF
    We are exploring the idea that early language acquisition could be better modelled on an artifcial creature by considering the pragmatic aspect of natural language and of its development in human infants. We have implemented a system of vocal behaviors on Kismet in which "words" or concepts are behaviors in a competitive hierarchy. This paper reports on the framework, the vocal system's architecture and algorithms, and some preliminary results from vocal label learning and concept formation

    There are numerous ways to combat institutionalized oppression, such as racism, sexism, homophobia, transphobia, and violence. One way just so happens to be through the art. This piece explores identity groups who are discriminated against every day, which President Trump has only emphasized through his actions and words. It questions why the history of our country has divided people by the color of their skin, why powerful men can say what they please about the female body, why heterosexuality is the only sexual orientation, why people should fall on either side of a gender binary, and why violence has continually been used to target certain identities in this country. This piece speaks to underline the intersectionality of institutionalized systems of oppression and how just one part cannot be included without another
