Detecting and generating quantum correlations with thermal processes

Heat and thermal noise disturb fragile quantum systems and are often enemies of those who strive to realise quantum advantages in computing, sensing, or communication. Nevertheless, there are intricate links between thermodynamic quantities and quantum correlations, and thermodynamic processes can in certain cases be harnessed to support quantum information processing and to reveal properties of quantum systems. In this talk, I will discuss relations between thermal processes and quantum correlations. In particular, thermal entanglement engines that harness heat flows to generate entanglement, when such machines are possible and impossible, as well as how measurements of heat exchange can be used to witness the presence of quantum correlations and coherence.
