Scientists realize quantum bit with a bent nanotube

One of the biggest challenges in quantum science is to build a functioning quantum bit, the basic element for the quantum computer. An important theoretical candidate for such a quantum bit is using a bent carbon nanotube. Scientists at the Delft University of Technology and the Foundation for Fundamental Research on Matter (FOM), led by Professor Leo Kouwenhoven, have succeeded for the first time to create a working quantum bit using a carbon nanotube. On July 28 they published their results in Nature Nanotechnology.
