N. David Mermin is Horace White Professor of Physics Emeritus at Cornell University. He has received the Lilienfeld Prize of the American Physical Society and the Klopsteg Award of the American Association of Physics Teachers. He is a member of the U. S. National Academy of Sciences and the American Academy of Arts and Sciences. Professor Mermin has written on quantum foundational issues for several decades, and is known for the clarity and wit of his scientific writings. Among his other books are Solid State Physics (with N. W. Ashcroft, Thomson Learning 1976), Boojums all the Way Through (Cambridge University Press 1990), and It's about Time: Understanding Einstein's Relativity (Princeton University Press 2005).

'This is one of the finest books in the rapidly growing field of quantum information. Almost every page contains a unique insight or a novel interpretation. David Mermin has once again demonstrated his legendary pedagogical skills to produce a classic.' Lov Grover, Bell Labs
