Superconductivity is a fascinating phenomenon that allows us to observe quantum mechanical effects at the macroscopic scale. A tremendous importance of superconductivity for fundamental science can be seen from the fact that there are at least 12 Nobel laureates in physics, who obtained the price for research related to superconductivity. Besides being of tremendous interest in themselves and vehicles for development key concepts and methods in theoretical physics, superconductors have found important applications in modern society. Those range from high power applications and strong superconducting magnets used in medicine, diagnostics and particle accelerators; to most sensitive quantum devices capable of measuring about a trillionth part of the Earths magnetic field and a millionth part of the electron charge.
