30 Sep 2004 | | Subject: | quant-ph | | Abstract: | We propose an experiment to observe interference of a single electron as it is transported along two parallel quasi-one-dimensional channels trapped in a single minimum of a travelling periodic electric field. The experimental device is a modification of the surface acoustic wave (SAW) based quantum processor. Interference is achieved by creating a superposition of spatial wavefunctions between the two channels and inducing a relative phase shift via either a transverse electric field or a magnetic field. The interference can be used to estimate the decoherence time of an electron in this type of solid-state device. | | Source: | arXiv, quant-ph/0409219 | | Services: | Forum | Review | PDF | Favorites | |
