This invited paper by Handel, Truong, George, and Morkoç presents quantum 1/f noise as a new aspect of quantum physics in high-tech devices, sensors, nanostructures and systems, presented at ICNF 2007 in Tokyo. The comprehensive review examines how quantum 1/f noise represents a fundamental quantum mechanical phenomenon with broad technological implications across diverse applications including semiconductor devices, sensors, nanoscale structures, and complex systems, arguing for recognition of quantum 1/f noise as an essential consideration in modern quantum technology development.
