Abstract

Coherent control of two-level quantum systems is typically achieved using resonant driving fields, forming the basis of qubit operations. Here, we report a mechanism for inducing complete Rabi oscillations in monochromatically driven two-level systems even when the drive frequency is much larger than the qubit’s Larmor frequency. This effect—Rabi oscillations induced by nonresonant gyrating drive (RING)—requires a gyrating control field, i.e., an elliptic drive trajectory that encloses a nonzero area per cycle. We illustrate the effect with numerical simulations and provide an analytical understanding via a simple effective Hamiltonian derived from Floquet theory and perturbation theory. We show that RING enables coherent oscillations without relying on resonant energy exchange, thereby allowing the integration of high-pass noise filtering. We detail a realization in electrically driven spin–orbit qubits, where the mechanism provides access to non-Abelian phases at nonzero magnetic field and enables amplification of the Rabi frequency using the same gate voltage amplitudes at higher drive frequencies. Our results broaden the landscape of quantum control by establishing a route to coherent manipulation under strongly off-resonant driving conditions.
