Entanglement detection via tighter local uncertainty relations Academic Article uri icon


  • We propose an entanglement criterion based on local uncertainty relations (LURs) in a stronger form than the original LUR criterion introduced by Hofmann and Takeuchi. Using arbitrarily chosen operators {k} and {Bk} of subsystems A and B, the tighter LUR criterion, which may be used not only for discrete variables but also for continuous variables, can detect more entangled states than the original criterion. 2010 The American Physical Society.
