Calarco T. - The world’s fattest Schrödinger cat - Colloquium DFA live

Giovedì 28 novembre 2019 - Ore 15:00 - Aula "A. Rostagni" Prof. Tommaso Calarco Institute Theoretical Physics, University of Cologne & Institute for Quantum Control of the Peter Grünberg Institute, Jülich Germany The world’s fattest Schrödinger cat Quantum optimal control enables efficient preparation of nonclassical states in many-body systems. Our new RedCRAB algorithm allows this to take place over an internet connection between the experiment and the optimisation server. I will report the application of this method to an method to an online competition among human “gamers”, as well as the creation of the largest entangled state to date (20 qubit in a GHz state).
