Lecture 5 of Leonard Susskind's course concentrating on Quantum Entanglements (Part 1, Fall 2006). Recorded October 23, 2006 at Stanford University.
The old Copenhagen interpretation of quantum mechanics associated with Niels Bohr is giving way to a more profoud interpretation based on the idea of quantum entanglement. Entanglement not only replaces the obsolete notion of the collapse of wave function but it is also the basis for Bell's famous theorem, the new paradigm of quantum computing, and finally the widely discussed "Many Worlds" interpretation of quantum mechanics of Everett. This course consists of parts I and III of a three part, year-long course series, but each course stands on its own and serves to look at some of the basics of quantum mechanics, entangement, Bell's theorem, elements of quantum computing, quantum teleportation, and similar material.
One of the world's leading universities, Stanford was founded in 1885 in what is now Stanford, California. It is comprised of seven schools, four of which are devoted exclusively to graduate education. Stanford's most renowned programs include the Graduate School of Business, Law School, School of Engineering, and School of Medicine. Notable alumni include author John Steinbeck, Supreme Court Justice William Rehnquist, and Google founders Sergey Brin and Larry Page.
