We research theoretically physical reservoir computing at finite temperature. Computing using the physical system should satisfy the echo state property (ESP); effects of initial state fade in time, for reproducibility of computation. We found the feasibility of the ESP becomes high if the temperature is low and the common input strength is high, and the ESP region becomes larger as time passes.
