We present an experimental realization of an autonomous Maxwell's demon, which extracts
microscopic information from a system and reduces its entropy by applying feedback. It is …

Classical and quantum electronic circuits provide ideal platforms to investigate stochastic
thermodynamics, and they have served as a stepping stone to realize Maxwell's Demons …

Maxwell's demon is an imaginary entity that reduces the entropy of a system and generates
free energy in the system. About 150 years after its proposal, theoretical studies explained …

We analyze a simple implementation of an absorption refrigerator, a system that requires
heat and not work to achieve refrigeration, based on two Coulomb-coupled single-electron …

Feedback control of quantum mechanical systems is rapidly attracting attention not only due
to fundamental questions about quantum measurements, but also because of its novel …

Sensitive charge detection has enabled qubit readout in solid-state systems. Recently, an
alternative to the well-established charge detection via on-chip electrometers has emerged …

We review recent progress in making the former gedanken experiments of Maxwell's demon
[1] into real experiments in a lab. In particular, we focus on realizations based on single …

We converted Gaussian-distributed voltage noise applied to an electron reservoir into the
non-equilibrium free energy of a nanometer-scale dot connected to the reservoir via an …

We measure the full distribution of current fluctuations in a single-electron transistor with a
controllable bistability. The conductance switches randomly between two levels due to the …

We performed electron counting statistics to measure the thermoelectric effect in a
nanometer-scale silicon dot. To separate the 100-nmlong dot from a silicon nanowire, we …
