DESCRIPTION:Entanglement entropy is a very important quantity in holograph
 y\, nevertheless it is only a measure of the total amount of entanglement 
 between two complementary subsystems in a global pure state. A more detail
 ed knowledge about the pattern of entanglement is essential for a deeper u
 nderstanding of the relation between bulk geometry and quantum information
  in the boundary theory. I will discuss how negativities and other measure
 s can be used in this context focusing in particular on qubit systems for 
 which a classification of possible entanglement structures is available.
