Logical stochastic resonance (LSR) is a paradigm to realize reconfigurable robust Boolean operations using specific nonlinearity in the presence of background noise. The stable-state number traditional LSR less than four, which restricts its upper limit heavy noise floor. To further improve robustness and output quality LSR, we proposed quadstable based system for first time this work. Using parameters determined by ant lion optimizer, compare performance (QLSR) tristable (TLSR) as logic gates results show that floor with intensity fluctuation, maximum QLSR can withstand significantly higher TLSR. When contains pulses, pulse TLSR comparable. Nevertheless, quantitative indexes reveal larger numbers endow stronger ability extract energy enhancing information; thus, better
