Quantum levitation or quantum locking is the ability of a superconductor to perfectly match the magnetic fields surrounding it.

Is quantum levitation possible?

While we don't have our hoverboards just yet, we do have the very real phenomenon of quantum levitation, which is almost as good. Under the right circumstances, a specially-made material can be cooled down to low temperatures and placed over a properly-configured magnet, and it will levitate there indefinitely.

Who invented quantum levitation?

You Can Experiment with Quantum Levitation […] In 1911, Dutch physicist and Nobel Laureate Heike Kamerlingh Onnes discovered that when you cool the element mercury (Hg) in liquid helium to a temperature of -270°C (-454°F) , it exhibits a phenomenon of zero electrical resistance, which he then called superconductivity.
