Deffner, Sebastian2019-12-192019-12-192019-10-16Deffner, Sebastian; Quantum speed limits and the maximal rate of entropy production; Quantum Physics; https://arxiv.org/abs/1910.06811http://hdl.handle.net/11603/16920The Bremermann-Bekenstein bound sets a fundamental upper limit on the rate with which information can be processed. However, the original treatment heavily relies on cosmological properties and plausibility arguments. In the present analysis, we derive equivalent statements by relying on only two fundamental results in quantum information theory and quantum dynamics -- Fannes inequality and the quantum speed limit. As main results, we obtain Bremermann-Bekenstein-type bounds for the rate of change of the von Neumann entropy in quantum systems undergoing open system dynamics, and for the rate of change of the Shannon information over some logical basis in unitary quantum evolution.6 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
