Majorana fermions can protect quantum states from decoherence and therefore are potential candidates to implement quantum information in superconduting heterostructures.
I address the interplay between Majorana fermions and charging energy in superconducting systems with Josephson junctions. First, I discuss the Coulomb stability of the fractional Josephson effect, an important signature of Majorana fermions, in a DC squid setup.
In the second part of the talk I present a scenario to realize braiding of Majorana fermions in Josephson junction networks, by simple manipulations of capacitive couplings and magnetic fluxes.
