We discuss the use of Tubular Image States (TIS) of electrons in the vicinity of nanotubes as a new vehicle for controlling and optically addressing nanoscale devices. We show that the stability of the TIS arises from the interplay between the attractive image potentials and the repulsive centrifugal potentials arising from the rotation of the electron about the cylindrically shaped nanotubes. We discuss the theory and some of the potential applications of TIS, and, in particular, the trapping of a single electron by a quadrupole made up of four nanotubes in the so‐called “nano‐Paul trap” configuration.
