This thesis presents an experimental study of quantum memory based on cold atomic ensembles and discusses photonic entanglement. It mainly focuses on experimental research on storing orbital angular momentum, and introduces readers to methods for storing a single photon carried by an image or an entanglement of spatial modes. The thesis also discusses the storage of photonic entanglement using the Raman scheme as a step toward implementing high-bandwidth quantum memory. The storage of photonic entanglement is central to achieving long-distance quantum communication based on quantum repeaters and scalable linear optical quantum computation. Addressing this key issue, the findings presented in the thesis are very promising with regard to future high-speed and high-capacity quantum communications.

The International Conference on Intelligent Computing (ICIC) was formed to provide an annual forum dedicated to the emerging and challenging topics in artificial intelligence, machine learning, bioinformatics, and computational biology, etc. It aims to bring - gether researchers and practitioners from both academia and industry to share ideas, problems, and solutions related to the multifaceted aspects of intelligent computing. ICIC 2009, held in Ulsan, Korea, September 16-19, 2009, constituted the 5th - ternational Conference on Intelligent Computing. It built upon the success of ICIC 2008, ICIC 2007, ICIC 2006, and ICIC 2005 held in Shanghai, Qingdao, Kunming, and Hefei, China, 2008, 2007,...
The most authoritative life of the Chinese leader every written, Mao: The Unknown Story is based on a decade of research, and on interviews with many of Mao’s close circle in China who have never talked before — and with virtually everyone outside China who had significant dealings with him. It is full of startling revelations, exploding the myth of the Long March, and showing a completely unknown Mao: he was not driven by idealism or ideology; his intimate and intricate relationship with Stalin went back to the 1920s, ultimately bringing him to power; he welcomed Japanese occupation of much of China; and he schemed, poisoned, and blackmailed to get his way. After Mao conquered China in 1949, his secret goal was to dominate the world. In chasing this dream he caused the deaths of 38 million people in the greatest famine in history. In all, well over 70 million Chinese perished under Mao’s rule — in peacetime.
This book - in conjunction with the volume LNAI 5755 - constitutes the refereed proceedings of the 5th International Conference on Intelligent Computing, ICIC 2009, held in Ulsan, South Korea in September 2009. The 214 revised full papers of these two volumes were carefully reviewed and selected from a total of 1082 submissions. The papers are organized in topical sections on Supervised & Semi-supervised Learning, Machine Learning Theory and Methods, Biological and Quantum Computing, Intelligent Computing in Bioinformatics, Intelligent Computing in Computational Biology and Drug Design, Computational Genomics and Proteomics, Intelligent Computing in Signal Processing, Intelligent Computing i...
In 1861, James Clerk-Maxwell published Part II of his four-part series 'On physical lines of force'. In it, he attempted to construct a vortex model of the magnetic field but after much effort neither he, nor other late nineteenth century physicists who followed him, managed to produce a workable theory. What survived from these attempts were Maxwell's four equations of electrodynamics together with the Lorentz force law, formulae that made no attempt to describe an underlying reality but stood only as a mathematical description of the observed phenomena. When the quantum of action was introduced by Planck in 1900 the difficulties that had faced Maxwell's generation were still unresolved. Since then theories of increasing mathematical complexity have been constructed to attempt to bring the totality of phenomena into order with little success. This work examines the problems that had been abandoned long before quantum mechanics was formulated in 1925 and argues that these issues need to be revisited before real progress in the quantum theory of the electromagnetic field can be made.
There are numerous “order of battle” books on the market. So what makes this one so special? Why should one decide on this particular book? Most “order of battle” books usually deal only at the division and corps level of a country’s army. Most higher commands are not covered. This book deals with all the branches of a country’s military, giving a breakdown of all the major echelons of command, from theater down to brigade, under each component (army groups, armies, corps, divisions, and brigades), and the equivalent command structure for the other military branches are included. Second, it attempts to give an overall command structure of the country’s military, showing the central headquarters command structure as well as the major components (army groups, armies, corps, etc.). Third, most “order of battle” books list the commander and their dates of tenure. This book includes those but also lists their next duty assignments or where they went after leaving the post. One can literally trace a general officer’s career through the upper echelons of command, making this completely different from all the other books on order of battle in the market.
Chu Yang liked Wei Qing for a long time. Wei Qing, on the other hand, didn't like the first rays of the sun. Honestly speaking, he didn't like anyone, only himself. But being forced by his father, he had no choice but to marry Chu Yang. After Wei Qing and Chu Yang's interview, he found out that the other party was very suitable in every aspect. He decisively signed a contract with Chu Yang to let him be the fake marriage partner. The first rays of the sun 'married' to Wei Qing as he wished. Initially, he thought that life after marriage would be as cold as ice. Unexpectedly, life after marriage would be as sweet as honey. Couples sow dog food together.
