Quantum causality: fundamentals and quantum information applications
Caslav Brukner, University of Vienna
Research on quantum causal structures is a new and rapidly developing field that has the potential not only to achieve advanced functionalities of information processing, but also to make a radical departure from the classical understanding of spacetime with fixed causal structures. In my talk, I will present recent results of quantum information processing on indefinite causal structures that show sublinear advantages in query complexity and exponential advantages in communication complexity.
