Fano Resonance is a phenomenon observed in quantum systems where interference occurs between a discrete state and a continuum of states. This results in an asymmetric line shape in the spectrum, which can be seen in various physical systems, including optical and electronic devices. The effect is named after Ugo Fano, who first described it in the 1960s. Fano Resonance is significant in fields like nanophotonics and quantum computing, as it can enhance the sensitivity of sensors and improve the performance of lasers and other optical components.
