Abstract
In this study, we theoretically analyzed a control protocol based on “time-dependent resonance” in nearly adiabatic two-level quantum systems, demonstrating that it exhibits properties equivalent to adiabatic control. This protocol is based on “time-dependent resonance,” where the frequency corresponds to the time-dependent energy gap. Through numerical calculations, we showed that this protocol serves as an optimal control protocol. This approach enables efficient and high-precision transitions to the target state. Our findings provide an alternative perspective on quantum optimal control theory and suggest potential applications in qubit controls and quantum information processing.
