Abstract: We consider a thermodynamic framework to quantify instrument incompatibility through a resource theory subject to thermodynamic constraints. In this resource theory, we use the minimal thermalisation time needed to erase incompatibility’s signature to measure how incompatible an instrument is. We show that this measure has a clear operational meaning in some work extraction tasks, thereby uncovering the thermodynamic advantages of incompatible instruments. We further analyse the possibility and impossibility of extending the time for incompatible signature to survive under general evolution. Finally, we discuss the physical implications of our findings to measurement incompatibility and steering distillation.
