This paper is really not meant for the layman. Even PhD physicists would find it terse unless they are working in the field of quantum information or AMO physics. However, there are many exciting and great resources where anybody interested can learn more about advanced physics. "The Theoretical Minimum" or Feinman's Lecture series are a great long on boarding experience that starts slow but gets pretty serious towards the end. And many researchers have more pop-sci type of blogs and media materials for those that want just a quick fix.
