电子量子霍尔干涉测量的多通道结构

Multi-channel architecture for electronic quantum-Hall interferometry

Vittorio Giovannetti, Fabio Taddei, Diego Frustaglia, Rosario Fazio

摘要:

我们提出了一种新的架构,实现量子霍尔条的电子干涉。它利用平行边缘通道之间的散射。与以前的发展相比,这一个采用了一个简单的连接台面承认串行级联的建筑元素更接近光学模拟。马赫-曾德尔和Hambury-Brown-Twiss干涉仪的实现与量子电子学中尚未探索的新结构一起讨论。

英文摘要:

We propose a new architecture for implementing electronic interferometry in quantum Hall bars. It exploits scattering among parallel edge channels. In contrast to previous developments, this one employs a simply-connected mesa admitting serial concatenation of building elements closer to optical analogues. Implementations of Mach-Zehnder and Hambury-Brown-Twiss interferometers are discussed together with new structures yet unexplored in quantum electronics.
