论文摘要
电动旋转共振(EDSR)是用于控制半导体旋转量子的建立工具。在这里,我们从理论上研究了EDSR的频率混合变体,其中应用了两个具有不同驱动频率的驱动音调,共振条件将旋转larmor频率与两个驱动频率的总和连接起来。为了关注翻转模式操作,我们计算了狂犬病频率和bloch-siegert偏移的参数依赖性。共享控制的自旋量子架结构可以从这种双重EDSR方案中受益,因为它可以同时使用单量门门。
Electrically driven spin resonance (EDSR) is an established tool for controlling semiconductor spin qubits. Here, we theoretically study a frequency-mixing variant of EDSR, where two driving tones with different drive frequencies are applied, and the resonance condition connects the spin Larmor frequency with the sum of the two drive frequencies. Focusing on flopping-mode operation, we calculate the parameter dependence of the Rabi frequency and the Bloch-Siegert shift. A shared-control spin qubit architecture could benefit from this bichromatic EDSR scheme, as it enables simultaneous single-qubit gates.
