In scenarios coined Maxwell's demon, information on microscopic degrees of freedom is used to seemingly violate the second law of thermodynamics. This has been studied in the classical as well as the quantum domain. In this paper, we study an impleme

Quantum technologies and experiments often require preparing systems in low-temperature states. Here, we investigate cooling schemes using feedback protocols modeled with a Quantum Fokker-Planck Master Equation (QFPME) recently derived by Annby-Ander

We devise an autonomous quantum thermal machine consisting of three pairwise-interacting qubits, two of which are locally coupled to separate classical reservoirs. The machine operates autonomously, as it requires no time-coherent control, external d

Quantum thermal machines can generate steady-state entanglement by harvesting spontaneous interactions with local environments. However, using minimal resources and control, the entanglement is typically very noisy. Here, we study entanglement genera

Syfte - Precis som samhället i övrigt digitaliserar Försvarsmakten sin verksamhet i ökande grad. Det höjer förmågan men ökar riskerna för cyberangrepp. Som en av flera åtgärder introducerade därför Försvarsmakten personalkategorin cyber

Temperature estimation plays a vital role across natural sciences. A standard approach is provided by probe thermometry, where a probe is brought into contact with the sample and examined after a certain amount of time has passed. In many situations

Sverige har en stigande befolkning som blir äldre, vilket ger en påfrestning av vårat hälsosystem1. Rädslan av att ramla i duschen hos äldre är stor och det gör att många väljer att sitta ner i duschen. Detta betyder inte att dom inte har k

Measurement and feedback control are essential features of quantum science, with applications ranging from quantum technology protocols to information-to-work conversion in quantum thermodynamics. Theoretical descriptions of feedback control are typi
