Normal modes of a superconducting transmission-line resonator with embedded lumped element circuit components

Henrik Lund Mortensen, Klaus Mølmer, Christian Kraglund Andersen

摘要:

本文提出了一种识别超导传输线耦合简正模的方法。我们评估的有效传输线的非线性的情况下,克尔类约瑟夫森相互作用的电路中,并在嵌入式电路构成量子位自由度的情况下,这是拉比耦合到传输线中的字段。我们的理论定量地解释了在最近的实验中观察到的非常高的正克尔非线性[M。Kazak等人,应用物理信函104,162604],并且我们可以评估实验电路的修改版本的成就。

英文摘要:

We present a method to identify the coupled, normal modes of a superconducting transmission-line with an embedded lumped element circuit. We evaluate the effective transmission-line non-linearities in the case of Kerr-like Josephson interactions in the circuit and in the case where the embedded circuit constitutes a qubit degree of freedom, which is Rabi coupled to the field in the transmission-line. Our theory quantitatively accounts for the very high and positive Kerr non-linearities observed in a recent experiment [M. Rehák et.al., Appl. Phys. Lett. 104, 162604], and we can evaluate the accomplishments of modified versions of the experimental circuit.
