Cover Story: The quest to invent thermal machines at the nanoscale has led to the new field of quantum thermodynamics. Recent technological advancement has enabled the experimental realization of quantum thermal machines powered by measurements and feedback, such as Maxwell’s demons and Szilard’s engines. These are devices where measurements and feedback allow, respectively, the extraction of heat or work from a single thermal bath. We study two different configurations of coupled-qubit-based thermal devices powered by discrete as well as continuous weak quantum measurements, namely a quantum Maxwell’s demon, and a measurement-assisted refrigerator. The measurement-assisted refrigerator extracts heat from a cold bath, exploiting the combination of external work and invasive quantum measurements. View this paper
