The New Quantum Age: From Bell's Theorem to Quantum Computation and Teleportation (Hardcover)

While quantum theory has been used to study the physical universe with great profit, both intellectual and financial, ever since its discovery eighty-five years ago, over the last fifty years we have found out more and more about the theory itself, and what it tells us about the universe. It seems we may have to accept non-locality - cause and effect may be light-years apart; loss of realism - nature may be fundamentally probabilistic; and non-determinism - it seems that God does play dice! This book, totally up-to-date and written by an expert in the field, explains the emergence of our new perspective on quantum theory, but also describes how the ideas involved in this re-evaluation led seamlessly to a totally new discipline - quantum information theory. This discipline includes quantum computation, which is able to perform tasks quite out of the range of other computers; the totally secure algorithms of quantum cryptography; and quantum teleportation - as part of science fact rather than science fiction. The book is the first to combine these elements, and will be of interest to anybody interested in fundamental aspects of science and their application to the real world. 

量子理論自85年前的發現以來，一直以來都被用來研究物理宇宙，並從中獲得了巨大的智力和財務收益。然而，在過去的50年裡，我們對這個理論本身以及它對宇宙的解釋有了越來越多的了解。似乎我們必須接受非局部性 - 因果關係可能相隔數光年；失去現實性 - 自然可能根本是概率性的；以及非確定性 - 看來上帝確實在玩骰子！這本書由該領域的專家撰寫，完全更新，解釋了我們對量子理論的新觀點的出現，並描述了這一重新評估中涉及的思想如何無縫地引導到一個全新的學科 - 量子信息理論。這個學科包括量子計算，能夠執行其他計算機無法完成的任務；量子密碼學的完全安全算法；以及量子傳輸 - 作為科學事實而非科幻。這本書是第一本結合這些元素的書籍，對任何對科學的基本方面及其應用於現實世界感興趣的人都會有興趣。
