Transfer of information in Parrondo's games

Amengual, Pau ; Toral, Raúl
Fluctuation and Noise Letters 5, L63-L71 (2005)

We study the relation between the discrete--time version of the flashing ratchet known as Parrondo's games and a compression technique used very recently with thermal ratchets for evaluating the transfer of information -- negentropy -- between the Brownian particle and the source of fluctuations. We present some results concerning different versions of Parrondo's games showing, for each case, a good qualitative agreement between the gain and the variation of the entropy.
