Josephson Tunnel and CQPS

Caption

This figure shows the Josephson tunnel (left) and coherent quantum phase slip (right). At left, two superconductors are separated by thin insulator (in this case space). A current is produced by superconducting electron pairs tunneling across the insulator. At right, two insulators are separated by superconductor. A current is produced by magnetic flux tunneling across the superconductor.
