Relativistic quantum information

Big question

How is the flow of information impacted by special and general relativity, and by quantum effects?

Basic idea

These phenomena can be studied by modeling the interaction of small quantum systems, such as atoms, with another, mediated through their interactions with quantum fields. Recent work with my students Robert Jonsson and Mathieu Cliche and my postdoctoral fellow Eduardo Martin-Martinez clarifies issues of causality, classical and quantum capacity and entanglement in the quantum channel that arises in this way.
