7. Distillability sudden death for two-qutrit states under an XY quantum environment.

Abstract

In this study, we investigate the phenomenon of distillability sudden death (DSD) for a two-qutrit system coupled to an XY spin chain. In virtue of the negativity and realignment criterion, we show that certain initial-prepared free entangled states may become bound entangled states in a finite time. The possibility of a DSD not only depends on the initial state parameter, but is also determined by the coupling between the two-qutrit system and the spin chain. The effects of other parameters related with the system and the spin chain (e.g., the total number of spins in the spin chain, strengths of the transverse field, and anisotropy parameter) on the time-determined bound entangled state are also investigated in detail. Accordingly, some effective methods of controlling the DSD are proposed. [ABSTRACT FROM AUTHOR]
