我们研究了 Dzyaloshinski-Moriya (DM) 各向异性反对称相互作用对双量子位海森堡链中纠缠和隐形传态的影响，并考虑了内在退相干。主要结果是对负性和完全纠缠分数的演化作为 DM 相互作用 D 和时间 t 的函数进行了系统分析。给出了最大纠缠初始状态和非纠缠初始状态的情况之间的对比。
We studied the effects of Dzyaloshinski–Moriya (DM) anisoyropic antisymmetric interaction on entanglement and teleportation in a two-qubit Heisenberg chain with intrinsic decoherence taken into account. The main result is the systematic analysis of the negativity and fully entangled fraction’s evolution as a function of DM interaction D and time t. The contrast between the case of the maximally entangled initial state and unentangled ones is presented.
