Before revision: Copying information is a fundamental task of biological systems that has to be performed at a finite temperature. There is agreement that this fact alone implies a lower limit on the error rate. However, contrasting results have been obtained regarding how this limit is approached. For instance, it is not clear when it can be achieved in a slow, quasi-adiabiatic regime or in a fast and highly dissipative one.
After revision: We study stochastic copying schemes in which discrimination between a right and a slow, quasi-adiabiatic regime or in a fast and highly dissipative one.
