Decay estimates for continuous quantum systems by Marius Junge, University of Illinois

We study quantum dynamical systems and their return and decoherence times. It turns out that estimating these times theoretically requires deep tools from geometry and mathematical physics. Our main goal is to obtain decay estimates for relative entropy. We will indicate how these return time estimates can be used to simulate the channel behavior of black holes with the help of random gates. This is joint work with Haojian Li and Nick LaRacuente.
