| Distinct from | berut2012experimental The Nature letter and the full account of the same experiment. berut2012experimental is the 2012 measurement of Landauer's bound in a colloidal-particle memory, four pages and held as a citation only; this is the same group's 27-page treatment in the Journal of Statistical Mechanics three years later, with the experiment set out at length. The corpus can read the second and not the first. |

Abstract
We present an experiment in which a one-bit memory is constructed, using a system of a single colloidal particle trapped in a modulated double-well potential. We measure the amount of heat dissipated to erase a bit and we establish that in the limit of long erasure cycles the mean dissipated heat saturates at the Landauer bound, i.e. the minimal quantity of heat necessarily produced to delete a classical bit of information. This result demonstrates the intimate link between information theory and thermodynamics. To stress this connection we also show that a detailed Jarzynski equality is verified, retrieving the Landauer's bound independently of the work done on the system. The experimental details are presented and the experimental errors carefully discussed
