Propagating quantum information in nanotubes
Carbon nanotubes are a new form of carbon that are proving to have many uses in nanoscience and nanotechnology. From the point of view of quantum information perhaps their most useful property is their ability to carry electrons very long distances without disrupting the direction of the tiny magnetic moment (or ‘spin’). They therefore have the potential to act as quantum "interconnects" within a quantum information processing device. This project will investigate the communication between mobile electrons in a nanotube with static electrons, localized nearby, that might act as repositories of quantum information. For example, the static electrons might reside on other chemical species introduced inside the nanotube in a ‘filling’ experiment.
