Quantum Egg-Box (IMAGE) University of Vienna Caption The principle of the fabrication of a "quantum egg-box" with a novel masked ion-beam technology, developed by the researchers. It allows to produce at the same time hundreds of thousands of traps for fluxons, magnetic flux quanta, in a superconductor. The picture at the bottom shows an electron-microscope image of the surface of the superconductor with some of these traps.
