Scattering and quantum information
In high energy and gravitational physics, the S-matrix is the starting point for studying any fundamental physics in asymptotically flat spacetimes. In the context of information theory, the S-matrix can be viewed simply as one of many possible unitary time evolution operators. I'll give some simple examples highlighting the overlap of these views; in particular, I will discuss the interplay of entanglement with relativistic scattering.
