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 {Âk} and {B□k} 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.
