The effects of quantum locking can only be experienced when using type II superconductors since type II superconductors can allow for small amounts of magnetic field penetration. Once the material has been cooled down to a point of superconductivity and is placed over a magnet, a very small portion of the magnetic strands, called fluxons, coming out of the magnet are able to penetrate the superconductor. Once the magnetic field lines have penetrated the imperfections of the type II superconductor, the superconductor will try to lock these fluxons in place. The fluxons are locked in place because any movement from the fluxons would create a release of energy and therefore break the material's superconductive state. The locking of these fluxons inside the superconductor is called quantum locking. By locking the fluxons, the superconductor is suspended in mid air above the magnet in whichever position it is left in.
