Quantum Levitation

Roughly defining, it’s levitating a superconductive object within a magnetic surface using the features of quantum physics.

How Does It Levitate?

When a superconductive object is placed on a magnetic disc, the strong magnetic surface of the disk causes the superconductive object to levitate. Of course there’s a limit and explanation to how distant the superconductive can stay from the disc’s surface. The distance between is determined by the magnetic surface power and the gravity force power duo. 

A disc created by the superconductives will show the “excellent diamagnetism” effect called “Meissner” on extreme levels. This superconductive will not contain any kind of magnetic surface inside of it and will levitate by avoiding contact with the magnetic surface. Though the only problem here is the levitating that’ll perform won’t be stable enough. This meaning that the object that’s levitating won’t be able to stay still. For quantum levitation to be useful, it needs to be stable. In situations like this, the thing we call “quantum locking” comes to place.

It needs to be more stable for this quantum lifting or quantum locking to be useful. According to Boaz Almog from Tel Aviv University “With the help of quantum locking, you can levitate a 1 ton car with only a 2 milimeters thick superconductive disc.” At the end of this article you can watch his speech about quantum locking on TED Talks.

Usage Areas

The “Maglev Train” used in Shanghai and the flying car modellings can use for quantum levitation however, for the “flying car” modellings a big and strong magnetic field and nitrogen to cool the superconductive are necessary. This is a problem. We can say that the fact that the superconductive requires cooling is a disadvantage.
