Roland Piquepaille at ZDNet reports that scientists at the Max Planck Institute in Germany have constructed a single-photon server with just one atom. Piquepaille reports that the ability to generate single photons may help the field of quantum information processing.
I seriously don't understand the science. An abstract of the work may be read online if you do. Instead, what I find most fascinating about quantum computing is that for the first time in human history experimentation is running ahead of our ideas, of conceptualization, of theory. When it comes to quantum reality, knowing can only be had by doing.
