We take a closer look at quantum measurements through the lens of quantum thermodynamics. From this perspective, it becomes clear that the textbook description of quantum measurements is an idealised fiction that needs a lot of thermodynamic work to be approximated well. Additionally, we take a deeper look into the foundations and discuss the 'measurement equilibration hypothesis', the idea that unitary many-body dynamics can broadcast information on its path towards equilibrium, creating objectivity in an autonomous fashion. We work out conditions on the interaction Hamiltonian and structure of the problem.
