Query: Performance of shortcut-to-adiabaticity quantum engines   We consider a paradigmatic quantum harmonic Otto engine operating in finite
time. We investigate its performance when shortcut-to-adiabaticity techniques
are used to speed up its cycle. We compute efficiency and power by taking the
energetic cost of the shortcut driving explicitly into account. We analyze in
detail three different shortcut methods, counterdiabatic driving, local
counterdiabatic driving and inverse engineering. We demonstrate that all three
lead to a simultaneous increase of efficiency and power for fast cycles, thus
outperforming traditional heat engines.
