Detecting fractional Josephson effect through phase slip
Zhen-Tao Zhang, Zheng-Yuan Xue, Yang Yu
Fractional Josephson effect is a unique character of Majorana Fermions in topological superconductor system. This effect is very difficult to detect experimentally because of the d…
Landau-Zener-Stuckelberg-Majorana interference in a 3D transmon driven by a chirped microwave
Ming Gong, Yu Zhou, Dong Lan +8
By driving a 3D transmon with microwave fields, we generate an effective avoided energy-level crossing. Then we chirp microwave frequency, which is equivalent to driving the system…
Detection of small single-cycle signals by stochastic resonance using a bistable superconducting quantum interference device
Guozhu Sun, Jiquan Zhai, Xueda Wen +6
We propose and experimentally demonstrate detecting small single-cycle and few-cycle signals by using the symmetric double-well potential of a radio frequency superconducting quant…
Observation of coherent oscillation in single-passage Landau-Zener transitions
Guozhu Sun, Xueda Wen, Ming Gong +6
Landau-Zener transition (LZT) has been explored in a variety of physical systems for coherent population transfer between different quantum states. In recent years, there have been…
Experimental demonstrations of high-Q superconducting coplanar waveguide resonators
Haijie Li, Yiwen Wang, Lianfu Wei +6
We designed and successfully fabricated an absorption-type of superconducting coplanar waveguide (CPW) resonators. The resonators are made from a Niobium film (about 160 nm thick)…
Coupling mechanism between microscopic two-level system and superconducting qubits
Zhen-Tao Zhang, Yang Yu
We propose a scheme to clarify the coupling nature between superconducting Josephson qubits andmicroscopic two-level systems. Although dominant interest in studying two-level syste…
