Vandersypen team at TU-Delft cause electrons to jump between distant quantum dots


electrons transported between quantum dots...

Scientists from Delft University of Technology and the FOM Foundation have successfully allowed electrons to jump between quantum dots located far from each other. The electron jumped between the ends of a chain of three small semiconducting islands (so-called quantum dots) without crossing the island in the middle. This process makes it easier to use quantum dots in future quantum computers. The researchers published their findings on 28 April online in the journal Nature Nanotechnology.
