Abstract

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 online competition among human "gamers", as well as the creation of the largest entangled state to date (20 qubit in a GHz state).
