Hi all, Next week's talk will be at 5pm on Tuesday in HIT K51 by Stefan Hengl. See you there, Roger Title: Light Cones in Quantum Information Abstract: A priori, non-relativistic quantum mechanics does not set a speed limit to the propagation of information, correlation, or perturbation. However, a famous result from mathematical physics shows that, under weak assumptions about the underlying system, there is indeed a system-inherent bound on the maximal velocity. This so-called Lieb-Robinson bound (LRB) can be an extremely powerful tool in proofs in various research fields. In the talk I will motivate the LRB, briefly review recent publications, and report about progress in Johan's and my project.
