There is no Landauer Limit: Experimental tests of the Landauer principle

Power dissipation is one of the most important factors limiting the development of integrated circuits. This work will explore the limits of energy dissipation in computation and show that there is no “Landauer Limit” at k
_B
T ln2 as long as information is preserved. Experimental data is presented that demonstrates a dissipation of 0.04 k
_B
T, well below k
_B
T ln2. Simulation results for adiabatically clocked reversible circuits are presented showing dramatic reductions of power dissipation.
