Absolutely entangled sets of pure states for bipartitions and multipartitions
Absolutely entangled sets of pure states for bipartitions and multipartitions
A set of quantum states is said to be absolutely entangled when at least one state in the set remains entangled for any definition of subsystems, i.e., for any choice of the global reference frame. In this work we investigate the properties of absolutely entangled sets (AESs) of pure quantum …
