Logical response induced by temperature asymmetry

摘要: It is known that the reliable logical response can be extracted from a noisy bistable system at an intermediate value of noise strength when two random or periodic, two-level, square waveform serve as inputs. The asymmetry potential has very important role and dictates type operation, such and, exhibited by system. Here we show one construct logic gates with symmetric if states double-well are thermalized different heat baths. been found given state kept sufficiently low temperature compared to other, shows kind behavior (say, or). Interestingly, system's turns into other and) initial low-temperature well increased gradually quality first improves then weakens after passing through maximum particular value. However, reliability second (and) not good (or) depends on amplitude Still both kinds properly choosing well.
