通过具有Dzyaloshinskiii-Moriya相互作用x分量的两量子比特Heisenberg XXX链实现量子隐形传态
Quantum teleportation via a two-qubit Heisenberg XXX chain with x-component of Dzyaloshinskii-Moriya interaction
摘要：
本文研究了两量子比特Heisenberg XXX链与Dzyaloshinskiii-Moriya相互作用的x分量$D_x$的热纠缠和热混合纠缠的量子隐形传态.我们的研究结果表明，温度$T$，自旋耦合常数J，和x-组件$D_x$可能会影响纠缠的输出状态，因此，隐形传态协议的可能性。此外，这些结果表明，输出态的纠缠需要一个低温制度，弱Dzyaloshinskiii-Moriya相互作用，或反铁磁链。最后，信道变得纠缠，使得隐形传态协议是可以想象和可行的。
英文摘要：
In this paper, we investigate the thermal entanglement and teleportation of a thermally mixed entangled via a two-qubit Heisenberg XXX chain with the x-component $D_x$ of the Dzyaloshinskii-Moriya interaction. Our findings suggest that temperature $T$, spin coupling constant J, and the x-components $D_x$ may influence entanglement of the output states and, consequently, the possibilities of teleportation protocols. Furthermore, these results indicate that the entanglement of the output states requires a low-temperature regime, weak Dzyaloshinskii-Moriya interaction, or an antiferromagnetic chain. Finally, the channel becomes entangled, making the teleportation protocol conceivable and feasible.
