摘要:
我们通过实验研究了电感分流型transmon类人工原子,将其作为应对超导量子系统中低非谐性及强电荷色散需求挑战的替代方案。我们对多款几何结构与参数(约瑟夫森能量、电容)各异的器件进行了表征,发现实验结果与计算结果吻合良好。该方法既能保留transmon量子比特设计与制造技术的优势以及高相干性,还有望提升非谐性,为量子计算中可扩展多量子比特系统的研发提供了替代平台。
英文摘要:
We experimentally investigate inductively shunted transmon-type artificial atoms as an alternative to address the challenges of low anharmonicity and the need for strong charge dispersion in superconducting quantum systems. We characterize several devices with varying geometries and parameters (Josephson energies and capacitances), and find a good agreement with calculations. Our approach allows us to retain the benefits of transmon qubit engineering and fabrication technology and high coherence, while potentially increasing anharmonicity. The approach offers an alternative platform for the development of scalable multi-qubit systems in quantum computing.
