| 摘 要： | 超级量子失协因其具有超越普通量子失协和量子纠缠的特性受到人们的普遍关注。本文从理论上对比研究了含Dzyaloshinski-Moriya相互作用的Heisenberg XYZ模型处于热平衡下的超级量子失协和普通量子失协。研究发现,超级量子失协总是大于普通量子失协,而且Dzyaloshinski-Moriya相互作用对超级量子失协起着积极作用。最有意义的是温度对该模型中超级量子失协的影响比普通量子失协小得多。

| Abstract: | Super quantum discord gets widely attention because it has better property than normal quantum discord and quantum entanglement. This paper perform comparative theoretical study on the super quantum discord and normal quantum discord in thermal equilibrium Heisenberg XYZ model with Dzyaloshinski - Moriya interaction. It is found that the super quantum discord always larger than the normal quantum discord, and Dzyaloshinski - Moriya interaction plays a positive role to the super quantum discord. Finally, it is most meaningful that the super quantum discord in this model is little affected by temperature than normal quantum discord. |
