Building Predictable Quantum Dots
Many teams of nanoscientists around the world want to be the first one to build quantum computers. To achieve this goal, they're using artificial atoms -- also known as '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. Read more for other details, references and a picture showing a quantum dot bombarded with laser light.
