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

What is Quantum Levitation?

SLIDE 3

A superconductor is a material, that when cooled to a temperature below its critical temperature, it’s electrical resistivity goes to zero.

First discovered by: Heike Kamerlingh Onnes

What is a Superconductor?

SLIDE 4

Almost any material, if cooled enough, can be made into a superconductor. Even many materials which are insulators at room temperature can be superconductors when cooled to extremely low temperatures.

What is a Superconductor Made Of?

SLIDE 5

Elements : Al, Sn, Hg, Pb Alloys : Mercury or Yttrium based Organics : Carbon nanotubes Ceramics : LBCO, YBCO, TBCCO

SLIDE 6

Ceramics : Compound Critical Temp(K)

What Does Quantum Levitation Do?

Because of the zero resistance properties of superconductors we get an effect known as quantum

levitation. This phenomenon creates a magnetic locking

effect between the superconductor and the magnetic

field. Thus allowing the superconductor to levitate.

The Meissner Effect:

When a superconductor reaches its critical temperature all magnetic fields applied to it are excluded from the interior. In other words, the field will go around it, not through it.

Why It Happens

SLIDE 10

Supercurrents

When a superconductor at its critical temperature is exposed to a magnetic field currents are induced within

it. These currents then induce an opposing magnetic field. Due to the lack of any resistivity, the currents are

able to perfectly mirror the magnetic field applied to the superconductor. The currents also adjust instantaneously with any changes in the field from things such as movement. Thus a floating piece of superconductor will stay in any position it is left in and will follow a magnetic track.

SLIDE 11

The Meissner Effect can also be explained mathematically with the London Equations.

SLIDE 12

If a superconductor with a easily achievable critical temperature (ideally above room temperature) were to be found or if a system that could easily keep a superconductor at its critical temperature were to be invented…
