Abstract

Abstract Quantum battery charging in an optimized manner is of significance in quantum state engineering and technology. This paper presents an efficient scheme for rapidly charging a superconducting qutrit battery via shortcuts to adiabaticity. A qutrit battery of a superconducting quantum circuit having sufficient level anharmonicity is driven by two classical microwave fields, constituting an effective Λ -configuration interaction. Within the framework of invariant-based inverse engineering, the fast charging of the qutrit battery can be realized through suitably designing the Rabi frequencies without the restriction of adiabatic criterion. Numerical simulations showcase that high-efficiency charging could be obtained in the presence of noise decoherence and timing error. Thus the scheme could pave a feasible avenue to investigate qutrit battery charging in a fast and robust way in experiments.
