Superdense coding: how to send two bits using one qubit

Explains the superdense coding protocol, which lets someone send two classical bits of information using just a single quantum bit. Part of a series on “Quantum computing for the determined”. The full series is at: http://www.youtube.com/user/mnielsencourses?feature=mhum#p/c/1826E60FD05B44E4
