I also prove that the bipartite rank three entangled states are distillable under local operations and classical communication.
我们证明了秩等于三的双体纠缠态在局域操作和经典联系的条件下都是可提纯的。
The duration of bound-entangled state (non-distillable) is controlled by the resonant control laser and the detuning of the atomic frequency inside the gap with respect to the band-edge.
