This book does not take you through quantum computing in any logical way. The author does not explain where he is going with his lengthy examples in each section. Instead he tends to launch into hard to follow, artificially concocted examples with little rationale and then move to the next topic without a conclusion or a reason for why he put the reader through such boring experience. The discussion of the Bohr - Einstein debate told me nothing of what the debate was about and there are many references to the EPR without any real explanation of what was in it. There must be a better way to understand this subject else I will have to conclude that Einstein was right and God really does play dice. Give this book a miss... it is simply not worth the effort. Even my one star is generous.
