Quantum Theory for Google PageRank
Physicists in Italy led by Nicola Perra have now determined that 'the Google PageRank can be expressed in terms of a wave function obeying a Schroedinger-like equation.' Isn't that great? Well you might think so if your business, job or hobby involves search engine optimisation because the ultimate result of this is that once a pagerank has been determined, recalculating it based on changes to links coming in to your pages and site will be significantly faster. What this infers is that Google will be able to update your site's page rankings more quickly than it currently does.
Schröedinger's equation is central to quantum physics and describes how the quantum state of a system changes over time. Very simply, you put your particles into the equation and you can see what's going to happen to the particles over time. Perra's team swapped particles with pages and their interactions with incoming and outgoing page links. They then derive the pagerank. Because the equation is all about how it changes over time the equation can be tweaked by adding or removing linked pages to get the new pagerank. Well that's how I understand it anyway.
