摘要：
被俘获在液氦表面的电子是一种极为洁净的系统，有望用于可扩展量子比特平台。然而，超流体表面并非没有涨落，这类涨落可能导致电子量子化态的衰减与退相干。理解并抑制这些涨落，对氦上电子（eHe）量子比特技术的发展至关重要。近期已有研究利用超导共面波导（CPW）谐振器，探究了由低温恒温器机械振动引发的表面振荡。在本工作中，我们聚焦于亚赫兹频率范围，观测到表面振荡对被限制在微通道俘获器件中的电子的里德堡跃迁时间动力学有显著影响。我们提出了这类振荡的可能来源，并且发现振荡频率的相应估算值与观测结果合理吻合。
英文摘要：
Electrons trapped on the surface of liquid helium is an extremely clean system which holds promise for a scalable qubit platform. However, the superfluid surface is not free from fluctuations which might cause the decay and dephasing of the electrons quantized states. Understanding and mitigating these fluctuations is essential for the advancement of electrons-on-helium (eHe) qubit technology. Some work has been recently done to investigate surface oscillations due to the mechanical vibration of the cryostat using a superconducting coplanar waveguide (CPW) resonator. In the present work, we focus on a sub-hertz frequency range and observe a strong effect of surface oscillations on the temporal dynamics of the Rydberg transition of electrons confined in a microchannel trapping device. We suggest possible origin of such oscillations and find a reasonable agreement between the corresponding estimation of the oscillation frequency and the observed result.
