Ahem - not "Quantum Levitation" at all. It's just a Super conductor. You cool them to their correct temperature (think just a few degrees above absolute 0), and magnetic lines wrap around them, instead of interacting with them - hence they "Levitate", or in this case, are supported by a structure of magnetic field lines.
This is nothing new - I did this in my Intro to Nano tech class just the other week, and I go WIT. When they figure out how to make a superconductor that operates at room temp, let me know.
