Neuromorphic computing uses principles from neuroscience to create devices that mimic neural systems, achieving efficient brain-like processing. It combines photonics and neuromorphic architectures for high efficiency and connectivity. More Signal, Less Background: Improving Signal To Noise RatioThe path to improving signal-to-noise ratio - the ratio of the power of signal (desired input) to the power of background noise (undesired input) - is to reduce the power of the noise – less background.
