We monitor the microwave response of superconducting resonators and observe fluctuations in dissipation and resonance frequency. We present a unified model where the observed dissipative and dispersive effects can be explained as originating from a bath of fluctuating two-level systems. From these measurements, we quantify the number and distribution of the defects.","authors_text":"A. Megrant, A. N. Cleland, B. Chiaro, C. Neill, D. Sank, J. Kelly, John M. Martinis, J. Wenner, J. Y.
