Nanoscientists dream of developing a quantum computer, a device the size of a grain of sand that could be faster and more powerful than today's PCs. They've identified quantum dots as the most likely materials to build these machines, but have been puzzled by the dots' unpredictable behavior at the nanoscale. Now a team of Ohio University physicists thinks it's found the problem - and has proposed a blueprint for building a better quantum dot.
