IQIM Postdoctoral and Graduate Student Seminar
Thermodynamics with electrons in a circuit
Abstract: I will discuss our experiments on stochastic thermodynamics using single electrons . We have realized a Maxwell's demon in form of a Szilard's engine for an electron [2,3]. In this measurement we manage to convert information to energy at a rate of about 75% of kT log(2) in a cycle on the average. I will also discuss a recent experiment on an "all-in-one" autonomous Maxwell's demon. In the final part of the talk I present our on-going activity on quantum thermodynamics in superconducting circuits [4,5].
