It is found that two level systems in the surrounding insulator cannot be the dominant source of noise in small qubits and argued that electron traps in the Josephson barrier with large Coulomb repulsion would emit noise that agrees both in magnitude and in temperature dependence with experimental data.

It is argued that this noise is produced by spins at superconductor insulator boundary whose dynamics is due to RKKY interaction, and this mechanism explains size independence of the noise, different frequency dependences of the spectra reported in large and small SQUIDs, and gives the correct intensity for realistic parameters.
