I haven't been too impressed with the "Frontiers of Science" series to this point. The authors all appear to be from Australia. The problem hasn't been that though. The books seem to be incomplete somehow--as if they are abridgments of more complete works in which key elements were left out of these versions. In this case, Milburn frequently refers the reader to his previous work which he claims contains more complete explanations. Paul Davies, in the Foreword, claims that Milburn's "careful and thorough account of how entanglement leads to observations that are totally impossible in a classical world is the best I have read." It appears that he is referring to Milburn's other book though as he cites it in the same paragraph.

If the phrase "a single photon has the capacity to provide an endless stream of information" sparks your curiosity then you don't want to be ignorant of this field for long. The possibilities described, mostly near the end of the book, are fascinating even if a firm grip of quantum physics isn't held by the reader.

For me, at least, his twin analogies used for teaching quantum entanglement did more to confuse the topic than to convey the concept clearly. Someone with prior exposure to quantum physics may not feel the same way. There probably isn't a single work available that can clearly explain quantum physics. Repeated exposure through a variety of authors is probably the best way to achieve competence of the subject. Milburn states that even if a person can understand the processes and equations they still don't know the 'whys'. No one does. Perhaps that is why quantum physics is more difficult to grasp than other classical physics.

Milburn relies fairly heavily on the work of David Deutsch. A reader may want to go directly to Deutsch's own writings for a first hand taste of his ideas. Likewise with Richard Feynman.
