Experimental demonstration of information-to-energy conversion and validation of the generalized Jarzynski equality
Abstract
Feedback mechanisms such as the 'demon' in Maxwell's well-known thought experiment can, in principle, enable the transformation of information into energy, without violating the second law of thermodynamics. Such information-to-energy conversion by feedback control has now been demonstrated experimentally.
