Tel-Aviv University demos quantum superconductors locked in a magnetic field. Video courtesy of Association of Science – Technology Centers (ASTC), representing the science centre and museum field worldwide.

The experiment left no doubt that, as far as accuracy of measurement went, the resistance disappeared. .. [the material] has entered a new state … superconductivity.

Quantum Levitation

A thin superconductor layer (~1µm thick) is coated on a sapphire wafer. Quantum physics tells us that the magnetic field penetrates into the superconductor in the form of discrete flux tubes. The superconductor strongly pins these tubes, causing it to float in midair. This effect is called quantum levitation.

Suspending a superconducting disc above or below a set of permanent magnets. The magnetic field is locked inside the superconductor; a phenomenon called Quantum Trapping.
