The second law of thermodynamics presupposes a clear-cut distinction between the controllable and uncontrollable degrees of freedom by means of macroscopic operations. The state-of-the-art technologies in quantum information and nano-science seem to force us to abandon such a notion in favor of the distinction between the accessible and inaccessible degrees of freedom. In this talk, I will discuss the implications of this paradigm shift by focusing on how the second law of thermodynamics can be generalized in the presence of a feedback control . I will also discuss the minimum work required for measurement and erasure of information . The Jarzynski equality has to be generalized in the presence of feedback control , as confirmed experimentally using polystyrene beads . A quantum generalization of the Szilard engine will also be discussed .
