论文摘要
我们开发了一种新的光谱法，以快速，直观地表征两个微波晶状体耦合的半导体矩矩形矩形矩形矩值。当我们调整量子隧道耦合相对于中介光子的频率时，揭示了高度独特和独特的几何图案。这些模式与使用Tavis-Cummings模型的仿真非常吻合，并让我们很容易地识别出令人失望的空间中这两个量子位的不同参数制度。该方法可能是整体光谱工具箱中的重要组成部分，以快速表征多个腔QED耦合量子的某些集体特性。
We develop a new spectroscopic method to quickly and intuitively characterize the coupling of two microwave-photon-coupled semiconductor qubits via a high-impedance resonator. Highly distinctive and unique geometric patterns are revealed as we tune the qubit tunnel couplings relative to the frequency of the mediating photons. These patterns are in excellent agreement with a simulation using the Tavis-Cummings model, and allow us to readily identify different parameter regimes for both qubits in the detuning space. This method could potentially be an important component in the overall spectroscopic toolbox for quickly characterizing certain collective properties of multiple cavity QED coupled qubits.
