Fundamentals of Quantum Entanglement

F J Duarte


Quantum entanglement (QE) is one of the most mysterious and promising subjects in physics. With applications in cryptographic space-to-space, space-to-earth and fibre communications, in addition to teleportation and quantum computing, QE goes beyond fascination and into the pragmatic spheres of commerce and the military.

In this monograph the philosophical and physical routes to QE are explained in a methodical and detailed approach. Furthermore, the interferometric approach to the derivation of QE probability amplitudes for a pair and multiple-pairs of quanta is exposed step by step. Written by F J Duarte, an expert in the field of quantum optics, the text provides the first side-by-side description of the philosophical path and the physical path to quantum entanglement, and does so in a clear and cohesive manner. This is also the first book to describe and explain, in a transparent exposition, the interferometric derivation of the ubiquitous probability amplitude for quantum entanglement.

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.
