SUMMARY:CQE Seminar Series: Building the second quantum revolution by 
 training Schrödinger cats\, from very fat to very fast\, Wisconsin Qu
 antum Institute\, Tommaso Calarco\, Institute for Quantum Control\, Pe
 ter Grünberg Institute at Forschungszentrum Jülich
DESCRIPTION:Developing quantum technologies towards practical applicat
 ion requires exquisite control of the dynamics of multiqubit systems. 
 Quantum optimal control offers a natural\, and increasingly widespread
 \, way to achieve this to the maximum possible extent. I will introduc
 e the optimal control method we developed for quantum many-body system
 s and its remote closed-loop implementation RedCRAB\, and I will repor
 t recent results we obtained with it in various physical contexts from
  diamond color centres to atoms in optical trap arrays\, where we demo
 nstrated optimal preparation of a 20-qubit GHZ state as well as single
 -atom spatial superposition states at the quantum speed limit. I will 
 also put these specific efforts in the more global context of the Euro
 pean Quantum Technologies activities\, including recent developments t
 owards scientific cooperation with the US.
