DESCRIPTION:Reservoir engineering is a powerful tool that enables the robu
 st preparation of pure quantum states in noisy environments. It has been s
 uccessfully employed for the stabilization of squeezed and entangled state
 s in trapped atoms and ions\, circuit quantum electrodynamics and optomech
 anics. However\, despite the success\, bosonic reservoir engineering is cu
 rrently limited by the linear character of the evolution\, which restricts
  the set of target states to Gaussian ones.\nI will discuss a novel scheme
  for the unconditional preparation of pure non-Gaussian states of a target
  system. The target mode is nonlinearly coupled to an auxiliary damped mod
 e\, which acts as an engineered reservoir. For concreteness\, I will discu
 ss an optomechanical realization\, where mechanical target states are stab
 ilized in an optomechanical cavity that is parametrically coupled to both 
 the mechanical displacement and the displacement squared. I will show how 
 interesting families of non-Gaussian states\, such as the cubic phase stat
 e or (squeezed and displaced) finite superpositions of Fock states\, can b
 e prepared following this recipe.\n
