Coulomb blockade and single-electron tunneling are manifestations, at the macroscopic level, of the granularity of charge. These effects can occur in small capacitance junction systems, under conditions which are discussed in this article. We examine in particular how the zero-point electromagnetic fluctuations can eventually wash out the single-electron effects.
