this is really cool. i think this could change the world if used with its magnetic field. im talking UFOs and what not.

Do you know how much energy is required to cool of a metal so that it become a superconductor? And in addition the low temperature must be maintained. At this state there is not much application for superconducting magnetic levitation.

Non-superconducting magnetic levitation is used on experimental Mag-Lev trains.

See http://en.wikipedia.org/wiki/Mag-lev_train

Technologies with the word "quantum" in them, such as quantum levitation or quantum computing, generally require highly specific conditions that can only be achieved with not only vast amounts of energy but also very exacting engineering and operating conditions. So we see many interesting reports in the literature and elsewhere about amazing "quantum" feats, but shouldn't expect any of these to be in our homes for a very long time.

... or on a macro-economic scale.

Besides, quantum mag-lev works only between two objects, and would thus not work if only one object was involved - sorry, kids, but this rules out using mag-lev to propel a space-ship, and the weight and expense pretty much rules out its use in aircraft, as well.
