DESCRIPTION:Prof. Tommaso Calarco\, Institute for Complex Quantum Systems\
 , University of Ulm - Germany\nQuantum mechanics is at the basis of all pr
 esent-day information and communication technologies: to name just two exa
 mples\, transistors and lasers would be impossible to build without unders
 tanding the quantum behaviour of matter and light. But the control of indi
 vidual quantum systems has long been considered only a “thought experime
 nt”\, something only possible in theory. However\, today this is routine
 ly achieved in labs around the world\, and it is the basis of quantum tech
 nologies. After reviewing the main applications of quantum technologies\, 
 ranging from secure communications to ultra-high precision sensing and met
 rology\, and from extremely powerful computers to the simulation of comple
 x materials\, I will present the common vision underlying the recently pro
 posed Quantum Manifesto\, which will be a basis for the upcoming Flagship 
 initiative on Quantum Technologies.\n\nTo achieve this vision in real envi
 ronments\, we need to push our ability to control the dynamics of increasi
 ngly complex quantum systems to its limits. In the case of quantum systems
  with few particles\, the decoherence occurring due to the interaction wit
 h the environment hinders the realisation of desired processes. In quantum
  many-body systems\, the complexity of their dynamics makes the state prep
 aration by external manipulation more difficult. I will show that Quantum 
 Optimal Control Theory provides an effective strategy to overcome these pr
 oblems. Quantum coherence is used to achieve a desired target with high ac
 curacy\, even under real conditions. I will present current experiments th
 at have been made possible by our new optimal control algorithm\, and expl
 ain how we can use such methods to push the limits of the physical realisa
 tion of quantum technologies.\n\nBio: Prof. Dr. Tommaso Calarco (Institute
  for Quantum Complex System\, University of Ulm) has pioneered the applica
 tion of quantum optimal control methods to quantum computation and to many
 -body quantum systems. He is the director of the centre IQST\, which invol
 ves the University of Ulm\, Stuttgart and the Max Planck Institute for Sol
 id State Research. He is one of the author of the “Quantum Manifesto” 
 and scientific member of the “High Level Steering Committee for the Quan
 tum Technologies Flagship”.
