This ICNF 2019 paper by Handel presents quantum 1/f noise as a decoherence phenomenon. The research establishes rigorous theoretical connection between quantum decoherence theory and 1/f noise generation, showing that environmental interactions causing loss of quantum phase coherence necessarily produce 1/f spectral characteristics through the universal properties of quantum measurement and open quantum system dynamics, providing fundamental explanation for the ubiquity of 1/f noise across diverse physical systems.
