Abstract

考虑内在的 decoherence 效果， two-qubit 的纠纷各向异性的 Heisenberg XYZ 链面对 Dzyaloshinski Moriya (DM ) ，各向异性的 antisymetric 相互作用在这篇论文被调查。同时发生，纠纷的测量，被计算。与相比在 XY 飞机各向异性， DM 相互作用是另一种各向异性的反对称的交换相互作用。内在的 decoherence 显然压制纠纷的时间进化，这被显示出。当起始的状态是 |ψ (0 )= cosα|01 + sinα|10 并且削弱纠纷的度时， DM 相互作用仅仅对纠纷的时间进化起作用。在当系统开始在州的 |ψ (0 ) 时，飞机仅仅在纠纷的时间进化上影响的 XY 各向异性 = cosα|00 +sin α|11。足够地弱在飞机能有效地提高的 XY 各向异性纠纷的度。

Taking the intrinsic decoherence effect into account, the entanglement of a two-qubit anisotropic Heisenberg XYZ chain in the presence of the Dzyaloshinski–Moriya (DM) anisotropic antisymetric interaction is investigated in this paper. Concurrence, the measurement of entanglement, is calculated. Compared with the anisotropic in XY plane, the DM interaction is another kind of anisotropic antisymmetric exchange interaction. It is shown that the intrinsic decoherence obviously suppresses the time evolution of the entanglement. The DM interaction only acts on the time evolution of the entanglement when the initial state is |ψ(0)⟩ = cosα|01⟩ + sinα|10⟩ and weakens the degree of entanglement. The anisotropic in XY plane merely impacts on the time evolution of the entanglement when the system is initially in a state |ψ(0)⟩ = cosα|00⟩ +sinα|11⟩. The sufficiently weak anisotropic in XY plane can effectively enhance the degree of entanglement.
