Quantum Nanowires Slash Electrical Noise, Opening New Path for Ultralow-Noise Electronics Flicker Noise Explained at the Smallest Scales That familiar low-frequency fuzz that disrupts mobile phone calls stems from the way electrons move and interact within materials at the smallest scales. Known as electronic flicker noise , it typically arises when the flow of electrons is interrupted by various scattering processes inside conductive metals. The same type of noise undermines the sensitivity of advanced sensors and poses a significant challenge for quantum computers — machines expected to deliver unbreakable cybersecurity, perform vast calculations and simulate nature in unprecedented ways. UCLA Study Reveals a Quieter Quantum Transport Regime Now, a far quieter and more promising future may be emerging. In a study led by UCLA , researchers have demonstrated prototype devices that, beyond a certain voltage, conduct electricity with less noise than is seen in ordinary electron flow . T...
