本文研究了考虑本征退相干的两量子位海森堡XXZ链中不均匀磁场对量子纠缠和隐形传态的影响。详细研究了纠缠态和完全纠缠态分数与非均匀磁场b和时间t的关系。给出了纯态和混合态不同初始状态的对比。
We studied the effects of inhomogeneous magnetic field on entanglement and teleportation in a two-qubit Heisenberg XXZ chain with intrinsic decoherence taken into account. The dependences of the entanglement and fully entangled fraction on the inhomogeneous magnetic fields b and time t are investigated in detail. The contrast between different initial states, including pure and mixed states, is presented.
