Pure marketing. "Quantum levitation" is just flux pinning[1] as seen in all "high temperature" superconductors. All you need a chunk of type 2 superconductor, a strong magnet, and some liquid nitrogen. Note the 852 videos on youtube: http://www.google.com/search?q=superconductor+levitation&...
You can shell out 80 bucks and do it yourself: http://sargentwelch.com/superconductivity-suspension-and-lev... (LN2 not provided.)
There doesn't appear to be any novel physics here at all.
