Advancements in Quantum Computing: From Single-Molecule Electron Sources to Ultra-Thin Superconducting Ink.

Researchers at University of Tokyo, JTS PRESTO, Ludwig Maximilians Universität and Kindai University have demonstrated the modulation of an electron source by applying laser light to a single fullerene molecule. The technique could enable the integration of ultrafast switches into a single fullerene molecule, paving the way for the development of better performing computers and microscopic imaging devices. The researchers also propose an integration scheme that would allow the integration of as many switches as desired without the need to increase the size of devices. The method could also be applied in the field of electron microscopy.
