Researchers from the Kavli Institute of Nanoscience (Delft University of Technology) and the FOM Foundation have devised a new method for reading out the electron state in a carbon nanotube. They did this by 'stamping’ an individual nanotube on a chip. Then the electron state can be read out, as the nanotube remains very clean and controllable. Electrons in such a nanotube can acquire special quantum characteristics which make these structures interesting for future quantum computers. The readout of the electron states is a crucial step in this. The research team led by FOM workgroup leader professor Leo Kouwenhoven published the results in the October issue of Nature Nanotechnology.
