A piano for electrons in a carbon nanotube

Researchers at the Weizmann Institute of Science in Israel have developed a nanoassembly technique that has allowed them to create new types of electronic devices using carbon nanotubes. These devices consist of pristine nanotubes with large arrays of electrodes, allowing many individual electrons to be controlled and manipulated along a single nanotube. Such circuits might be used to investigate novel electron physics and nanoscale mechanics, and perhaps even to make chains of electron spins for quantum information processing…………….
