Скачать книгу - Entanglement

Unique in that it is jointly written by an experimentalist and a theorist, this monograph presents universal quantum computation based on quantum teleportation as an elementary subroutine and multi-party entanglement as a universal resource. Optical approaches to measurement-based quantum computation are also described, including schemes for quantum error correction, with most of the experiments carried out by the authors themselves. Ranging from the theoretical background to the details of the experimental realization, the book describes results and advances in the field, backed by numerous illustrations of the authors' experimental setups. Aimed at researchers, physicists, and graduate and PhD students in physics, theoretical quantum optics, quantum mechanics, and quantum information.

Melting point… .When Joanna refused to jump into bed with Alex Marshall, he assumed she was frigid! But the arrogant entrepeneur sensed that it wasn't just the intense Egyptian heat that was responsible for melting the cast-iron defenses that Joanna had erected since the end of her marriage!However, there wasn't any future in a no-strings affair – no matter how much she ached for Alex… .

Imperial Entanglements chronicles the history of the Haudenosaunee Iroquois in the eighteenth century, a dramatic period during which they became further entangled in a burgeoning market economy, participated in imperial warfare, and encountered a waxing British Empire. Rescuing the Seven Years' War era from the shadows of the American Revolution and moving away from the political focus that dominates Iroquois studies, historian Gail D. MacLeitch offers a fresh examination of Iroquois experience in economic and cultural terms. As land sellers, fur hunters, paid laborers, consumers, and commercial farmers, the Iroquois helped to create a new economic culture that connected the New York hinterland to a transatlantic world of commerce. By doing so they exposed themselves to both opportunities and risks. As their economic practices changed, so too did Iroquois ways of making sense of gender and ethnic differences. MacLeitch examines the formation of new cultural identities as men and women negotiated challenges to long-established gendered practices and confronted and cocreated a new racialized discourses of difference. On the frontiers of empire, Indians, as much as European settlers, colonial officials, and imperial soldiers, directed the course of events. However, as MacLeitch also demonstrates, imperial entanglements with a rising British power intent on securing native land, labor, and resources ultimately worked to diminish Iroquois economic and political sovereignty.
