This document discusses quantum levitation using superconductors. It begins by defining superconductivity as zero electrical resistance and magnetic field expulsion below a critical temperature. It then discusses Meissner effect and different types of superconductors. The document introduces the concept of quantum locking, where magnetic flux lines do not move inside an ultra-thin type-2 superconductor. Applications of quantum levitation include frictionless bearings, gravity manipulation, and lossless electrical machines. Future prospects include quantum levitation trains with greater stability than maglev trains.
