Aharonov-Bohm环中的手征纠缠

Chiral-mediated entanglement in an Aharonov-Bohm ring

Bruno Rizzo, Liliana Arrachea, Juan Pablo Paz

摘要:

研究了四端连接的有偏Aharonov-Bohm环中的轨道纠缠。我们发现当磁通量B与半磁通量量子的整数0 /2重合时,共生达到最大值。我们表明,这种行为是具有相反的手征环的简并状态的存在的后果。我们还分析了作为函数的噪声的行为,并讨论了这个量作为纠缠证据的可靠性。

英文摘要:

We study the orbital entanglement in a biased Aharonov-Bohm ring connected in a four-terminal setup. We find that the concurrence achieves a maximum when the magnetic flux B coincides with an integer number of a half flux quantum 0 /2. We show that this behavior is a consequence of the existence of degenerate states of the ring having opposite chirality. We also analyze the behavior of the noise as a function of and discuss the reliability of this quantity as evidence of entanglement.
