WTF? That's pretty awesome. I wasn't aware that macro-scale quantum solids even existed. The Bose-Einstein condensate is where my basic knowledge ends. Any idea what the material is?
Here's what was linked in the video description: http://www.quantumlevitation.com/levitation/The_physics.html
"We start with a single crystal sapphire wafer and coat it with a thin (~1µm thick) ceramic material called yttrium barium copper oxide (YBa2Cu3O7-x ). The ceramic layer has no interesting magnetic or electrical properties at room temperature. However, when cooled below -185ºC (-301ºF) the material becomes a superconductor. It conducts electricity without resistance, with no energy loss. Zero."
