There is a longstanding discussion about the question where exactly the border between the classical and the quantum world might lie and depends very much on which features of the world we define as non-classical in the first place. Entanglement is one of the few features that we tend to agree upon as being non-classical. Hence we decided to attack the question of non-classicality from the viewpoint of entanglement by examining which states can be interconverted into entangled states. The results that we obtain generalize and link convertibility properties from the resource theory of coherence, spin coherent states, and optical coherent states, while also revealing important connections between local and nonlocal pictures of non-classicality.
