Mesoscopic low frequency noise in electrical characteristics of disorderedconductors is a result of dynamic quantum interference pattern due to motion ofdefects. This has been firmly established by demonstrating the characteristicpartial suppression of the noise amplitude by the dephasing effect of a weakexternal magnetic field. The spatial correlation of the quantum interferencepattern in disordered normal state conductors is invariably limited by theexponential phase relaxation due to inelastic processes. In this paper wedevelop a quantitative theory of the mesoscopic noise in the s-wavesuperconducting phase of a strongly disordered superconductor (such that thesuperconducting coherence length is much longer than the mean free path). Wefind that the superconducting coherence length limits the quantum interferenceeffects in superconductors. However, in contrast to the normal phase, the decayof the phase relaxation on the scale of the superconducting coherence length isnon-exponential. This unusual slow relaxation manifests in the enhancedamplitude of the mesoscopic noise in superconductors and a peculiar non-linearscaling of the amplitude with the strength/number of mobile defects in verythin superconducting films and wires (effectively 2D and 1D with respect to thesuperconducting coherence length). Mesoscopic noise sets a natural limit on thequality of kinetic inductance elements.
