Title: Dense Coding Using Quantum Entanglement
Abstract:
Entanglement is a somewhat mysterious property of a quantum system, one with no direct classical analog. Dense coding is a process in which entanglement can be used to increase the capacity of a quantum channel to carry information by a factor of two, despite the fact that entanglement by itself does not transport information. The question addressed in this talk is how dense coding, both the original protocol (Bennett and Wiesner) and some more recent variations thereof, can help us understand entanglement and its role in quantum information theory.
