We study the application of a counter-diabatic driving (CD) technique toenhance the thermodynamic efficiency and power of a quantum Otto refrigeratorbased on a superconducting qubit coupled to two resonant circuits. Although theCD technique is originally designed to counteract non-adiabatic coherentexcitations in isolated systems, we find that it also works effectively in theopen system dynamics, improving the coherence-induced losses of efficiency andpower. We compare the CD dynamics with its classical counterpart, and find adeviation that arises because the CD is designed to follow the energyeigenbasis of the original Hamiltonian, but the heat baths thermalize thesystem in a different basis. We also discuss possible experimental realizationsof our model.
