Measuring the behaviour of electrons injected into quantum dots

Measuring the behavior of electrons injected into quantum dots promises insights into how electrons behave in complex real-world materials and could help researchers engineer devices that make possible  quantum computers, say scientists from the US National  Institute of Science and Technology (NIST). The researchers made multiple 3-by-3 grids of precisely spaced quantum dots, each comprising ...
