The difference between an 'ordinary' superconductor and a chiral one is that the electrons not only move through the material in pairs, but that the electrons in the pairs also rotate around one another. This produces an interesting effect: so called Majorana particles can form at the ends of a wire made of a chiral superconductor. These particles are expected to be the ideal quantum bits for a quantum computer. The existence of Majorana particles was predicted in 1937 by the Italian theoretical physicist Ettore Majorana, but was experimentally observed only recently by physicists at TU Eindhoven and TU Delft.

An ordinary superconductor can generate an electric current when a magnet is placed nearby. This is called the Meissner effect. The current in the superconductor creates an opposite magnetic field that cancels out the field from the magnet. One of the most remarkable applications of the Meissner effect is the Maglev trains in China and Japan, which can attain speeds of 600 kilometers per hour by floating above the track.
