Forbidden interval theorems state whether a stochastic-resonance noise benefit occurs based on whether the average noise value falls outside or inside an interval of parameter values. Such theorems act as a type of screening device for mutual-information noise benefits in the detection of subthreshold signals. Their proof structure reduces the search for a noise benefit to the often simple task...

Abstract The possibility of using weak optical signals to perform sensing delicate samples constitutes one the main goals quantum photonic sensing. Furthermore, nanoscale confinement electromagnetic near fields in platforms through surface plasmon polaritons has motivated development highly sensitive plasmonic sensors. Despite enormous potential for sensing, this class sensors is ultimately lim...
