Detection of bound entanglement in continuous-variable systems Academic Article uri icon


  • We present several entanglement conditions in order to detect bound entangled states in continuous-variable systems. Specifically, Werner and Wolf [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.86.3658 86, 3658 (2001)] and Horodecki and Lewenstein [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett. 85.2657 85, 2657 (2000)] have proposed examples of a bound entangled Gaussian state and a bound entangled non-Gaussian state, respectively, of which entanglement can be detected by using our entanglement conditions. 2010 The American Physical Society.
