Pseudo-Rabi oscillations in superconducting flux qubits in the classical regime

Pseudo-Rabi oscillations in superconducting flux qubits in the classical regime

Nonlinear effects in mesoscopic devices can have both quantum and classical origins. We show that a three-Josephson-junction (3JJ) flux qubit in the classical regime can produce low-frequency oscillations in the presence of an external field in resonance with the (high-frequency) harmonic mode $\ensuremath{\omega}$ of the system. Like in the case …
