Abstract
An efficient computer can be viewed as a thermodynamic engine where mechanical work is spent to reduce informational entropy. The authors implement a simple computing device approaching this ideal using the standard toolbox of superconducting flux circuits. The paper shows a work measurement from individual stochastic trajectories and verify a Fluctuation Theorem result that links the work distributions for bit reset and bit creation
