We propose an 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 analogs. Implementations of Mach-Zehnder and Hambury-Brown-Twiss interferometers are discussed together with structures yet unexplored in quantum electronics.

Abstract
We propose an 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 analogs. Implementations of Mach-Zehnder and Hambury-Brown-Twiss interferometers are discussed together with structures yet unexplored in quantum electronics.File in questo prodotto:
