It was pointed out by Fu and Kane [4], following a proposal in a different context by Sato [5], that the interface between a conventional superconductor and a topological insulator supports such Majorana levels in magnetic vortices, and that Majorana levels can lead to a modification of the Josephson effect.
A fundamental prediction of superconductivity theory has been demonstrated in the lab for the first time. An international team of physicists has observed coherent quantum phase slip, a phenomenon similar to the well-known Josephson effect in which magnetic flux takes the place of electric charge.
1) is similar to the flow of a supercurrent across a barrier between two superconducting regions (Josephson effect).

The Josephson effect is directly linked to superconductivity. Two superconducting materials, separated by a very thin barrier, can overlap their wave functions and Cooper pairs can tunnel through the barrier: This is known as the Josephson effect ...
For Entangled electron pairs superconducting spintronics, there exist two drawbacks in existing proposals of generating entangled electron pairs.
The quantum condensate of Cooper pairs forming a superconductor was originally conceived as being translationally invariant. In theory, however, pairs can exist with finite momentum Q, thus generating a state with a spatially modulated Cooper-pair density.

There have also been attempts to use the Josephson Effect to create ordinary processors. An experimental processor of this type was created in Japan in the late 1980s.
