    "abstract": "We propose an experiment to observe interference of a single electron as it\nis transported along two parallel quasi-one-dimensional channels trapped in a\nsingle minimum of a travelling periodic electric field. The experimental device\nis a modification of the surface acoustic wave (SAW) based quantum processor.\nInterference is achieved by creating a superposition of spatial wavefunctions\nbetween the two channels and inducing a relative phase shift via either a\ntransverse electric field or a magnetic field. The interference can be used to\nestimate the decoherence time of an electron in this type of solid-state\ndevice.",
