| Abstract | |
Protocols for nonadiabatic quantum control often require the use of classical time-varying fields. Assessing the thermodynamic cost of such protocols, however, is far from trivial. Here, we study the irreversible entropy produced by the classical apparatus generating the control fields, thus providing a direct link between the cost of a control protocol and dissipation. We focus, in particular, on the case of time-dependent magnetic fields and shortcuts to adiabaticity. Our results are showcased with two experimentally realizable case studies: the Landau-Zener model of a spin-21 particle in a magnetic field and an ion confined in a Penning trap. (AU) | |
