Shortcuts to adiabaticity constitute a powerful alternative that speed up time evolution while mimickingadiabatic dynamics. In this paper we describe how to implement shortcuts to adiabaticity for the case of amassless scalar field inside a cavity with a moving wall, in 1 + 1 dimensions. The approach is based on theknown solution to the problem that exploits the conformal symmetry, and the shortcuts take place wheneverthere is no dynamical Casimir effect. We obtain a fundamental limit for the efficiency of an Otto cycle withthe quantum field as a working system, that depends on the maximum velocity that the mirror can attain. Wedescribe possible experimental realizations of the shortcuts using superconducting circuits.
