Electrically driven spin resonance with bichromatic driving

Electrically driven spin resonance (EDSR) is an established tool for controlling semiconductor qubits. Here, we theoretically study a frequency-mixing variant of EDSR, where two driving tones with different drive frequencies are applied, and the condition connects Larmor frequency sum frequencies. Focusing on flopping-mode operation single electron in double quantum dot spin-orbit interaction, calculate parameter dependence Rabi Bloch-Siegert shift. A shared-control qubit architecture could benefit from this bichromatic EDSR scheme, as it enables simultaneous single-qubit gates.
