We discuss the implementation of a beam splitter for electron waves in a quantum Hall bilayer. Our architecture exploits interlayer tunneling to mix edge states belonging to different layers. We discuss the basic working principle of the proposed coherent edge mixer, possible interferometric implementations based on existing semiconductor-heterojunction technologies, and advantages with respect to canonical quantum Hall interferometers based on quantum point contacts.

Abstract

We discuss the implementation of a beam splitter for electron waves in a quantum Hall bilayer. Our architecture exploits interlayer tunneling to mix edge states belonging to different layers. We discuss the basic working principle of the proposed coherent edge mixer, possible interferometric implementations based on existing semiconductor-heterojunction technologies, and advantages with respect to canonical quantum Hall interferometers based on quantum point contacts.
