Multichannel architecture for electronic quantum Hall interferometry
Vittorio Giovannetti, Fabio Taddei, Diego Frustaglia, Rosario Fazio · Physical Review B · 2008
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.
