摘要: 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 optical analogs. Implementations Mach\char21{}Zehnder and Hambury\char21{}Brown\char21{}Twiss interferometers are discussed together with structures yet unexplored electronics.
