Building Predictable Quantum Dots

Roland Piquepaille writes "Many teams of nanoscientists around the world are using 'quantum dots.' But even if they're able to use them, not a single team has been able to consistently control their quantum mechanical states — or their properties — at the nanoscale. Now, a team from Ohio University claims it found a flaw in quantum dot construction and proposes a solution. And guess what? As it happens often in research, this new finding is based on a very simple fact: an interference between two physical phenomena.
