A cool book on a cool topic, Fundamentals of Quantum Entanglement manages to package a complex topic in a series of easier-to-swallow chapters. Of course, there are equations not for the faint of heart and there are the usual challenges of understanding quantum phenomena (with even more daunting math in the appendixes), but the author makes it all fun to read. This is a mathematically annotated history of science, illustrated with diagrams and backed up by extensive lists of references in each chapter. It is surprising how much the compact size of the chapters helps to give the reader a feeling of swift progress as each chapter is digested. The topics themselves are irresistible for the interested audience: teleportation (not of objects, but of quantum states), quantum communications and, of course, quantum computing-just a brief introduction without prime factoring algorithms. For readability and for excellent references, as well as for a tiny index, the book works well for anybody interested in the topic, but it lacks the problems that would make it suitable as a textbook.
