Trading resources in quantum Shannon theory

Presented by Mark Wilde, Louisiana State University

What are the net rates at which a sender and receiver can generate classical communication, quantum communication, and entanglement by using a quantum channel many times? A priori, this question might seem challenging, but there is a surprisingly simple answer for several channels of interest: Just combine a single protocol with the three basic protocols of teleportation, super-dense coding, and entanglement distribution. In this talk, I will discuss this theorem in some detail and show how the "triple trade-off" capacity region simplifies for a number of quantum channels of interest, including dephasing, erasure, and bosonic loss and amplifier channels.
