Introduction,systems. The field grew from the investigations of the physical limits to computation initiated by Charles Bennett and Rolf Landauer. One of the first questions studied was whether quantum mechanics imposes any limits on what a computer can do, and it was shown by Richard Feynman that it does not. E

Quantum Measurement Theory,valent to learning what final state the system is in at the output since information is encoded in the state. In fact, information is the state itself. Since finding out the state of a system can be done only by performing measurements on it, we need a thorough understanding of the quantum theory (a
