SUMMARY:Quantum control of continuous variables - Alessio Serafini (UCL)

DESCRIPTION:Achieving the coherent control of quantum systems is clearly t
 he central challenge on the way to operational quantum technologies. In th
 is talk\, we will review recent results in the field of control of quantum
  continuous variables\, such as electromagnetic field modes\, nano-mechani
 cal oscillators and trapped ions. In particular\, we will report on result
 s concerning the open-loop controllability of systems of coupled oscillato
 rs\, and flag up the relationship between recurrence and controllability i
 n such systems. Further\, we will address the optimisation of steady-state
  quantum entanglement by measurement-based feedback control in systems of 
 coupled harmonic oscillators\, under rather general\, unitary and dissipat
 ive\, dynamical conditions. Finally\, we will suggest some approaches for 
 the experimental implementation of the schemes discussed.
