Abstract

Erasure of memory is an essential part of information processing. We consider a photochemical model to suggest a protocol for chemical memory erasure. It has been shown that successful erasure may be achieved by a synergy between a very weak but optimal thermal noise and a minuscule linear bias. The suggested scheme for photochemical transformation can be viewed as a chemical analogue of memory erasure procedure.
