 (Universitat Autonoma de Barcelona)<br></span><br><span>We develop a gener
 al framework characterizing the structure and properties of quantum resour
 ce theories for continuous-variable Gaussian states and Gaussian operation
 s\, establishing methods for their description and quantification. We show
  in particular that\, under a few intuitive and physically-motivated assum
 ptions on the set of free states\, no Gaussian quantum resource can be dis
 tilled with free Gaussian operations\, even when an unlimited supply of th
 e resource state is available. This places fundamental constraints on stat
 e transformations in all such Gaussian resource theories. We discuss in pa
 rticular the applications to quantum entanglement\, where we extend previo
 usly known results by showing that Gaussian entanglement cannot be distill
 ed even with Gaussian operations preserving the positivity of the partial 
 transpose\, as well as to other Gaussian resources such as steering and op
 tical nonclassicality. A unified semidefinite programming representation o
 f all these reso urces is provided.<br></span><br>Related Links<ul><li><a
