Скачать или смотреть Quantum Noise: How Tiny Fluctuations Impact Sensory Detection

The video explores how quantum noise affects sensory systems like the human eye and various technologies. It highlights how particles like photons or electrons don't behave predictably, causing random variations in the signals we try to measure. This noise limits the precision of detecting weak signals, such as single photons or faint sounds, in both biological and electronic systems. The unpredictability of particles is tied to Heisenberg's uncertainty principle, making it challenging to extract pure information from faint signals.
