Description

Location: Room 5209

Using the operational framework of completely positive, trace preserving operations, thermodynamic fluctuation relations and fluctuation theorems, we derive a lower bound for the heat exchange in a Landauer erasure process on a quantum system. Our bound comes from a non-phenomenological derivation of the Landauer principle which holds for generic non-equilibrium dynamics.

Combining the two-time measurement protocol for the reconstruction of the statistics of heat with the minimal set of assumptions for Landauer’s principle to hold, we derive a general one-parameter family of upper and lower bounds on the mean dissipated heat from a system to its environment.

Experimental implementations will also be discussed. Info on speaker:
