Abstract: Sending and receiving quantum signals can boost the performance of communication systems and even let you do things that are impossible with classical signals. For example, a quantum communication channel can be used to transmit quantum information or establish entanglement between distant parties.  Even if the channel is noisy, quantum error correcting codes can allow information to be transmitted essentially perfectly. In this talk, I’ll discuss several questions about the theory of quantum communication: How much noiseless information can a noisy channel transmit? How much noise is too much? Can entanglement enhance the performance of purely classical networks? How can we quantify the correlations in a quantum state? And what does any of this have to do with physics anyway?
