In this project, we develop a novel route to overcome current problems with designing quantum technologies. The key idea is to combine shortcuts-to-adiabaticy and quantum thermodynamics. The potential for this merging is nearly self-explanatory: ideal thermodynamic processes are based on adiabatic processes which give maximum efficiency but unfortunately require infinite operation time; on the other hand, shortcuts-to-adiabaticy are techniques to speed-up adiabatic processes, e.g. the transport of Bose-Einstein condensate in anharmonic traps [1]. In line with this key idea, the technique of enhanced shortcuts to adiabaticity has been developed [2-3] and applied, for example, to spin squeezing in internal bosonic Josephson junctions [4]. In addition, quantum heat engines based on Bose-Einstein condensates have been studied. In detail, a novel quantum heat engine based on a spin-orbit- and Zeeman-coupled Bose-Einstein condensate has been proposed. The work and heat involved as well as the associated efficiency have been discussed [5]. Moreover, quantum control of the dynamics of a classical piston coupled to a Rabi-coupled Bose-Einstein condensate has been developed and optimised; the work involved in this has also been examined [6].
