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…
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…
Landau-Zener-Stuckelberg interference in a multi-anticrossing system
Jindan Chen, Xueda Wen, Guozhu Sun +1
We propose a universal analytical method to study the dynamics of a multi-anticrossing system subject to driving by one single large-amplitude triangle pulse, within its time scale…
Quantum nondemolition measurements of a flux qubit coupled to a noisy detector
Wei Jiang, Yang Yu, Lianfu Wei
We theoretically study the measurement-induced dephasing caused by back action noise in quantum nondemolition measurements of a superconducting flux qubit which is coupled to a sup…
Optimal cooling of a driven artificial atom in dissipative environment
Lingjie Du, Yang Yu
We study microwave-driven cooling in a superconducting flux qubit subjected to environment noises. For the weak decoherence, our analytical results agree well with the experimental…
Low-frequency Landau-Zener-Stückelberg interference in dissipative superconducting qubits
lingjie du, yang yu
Landau-Zener-Stückelberg (LZS) interference of continuously driven superconducting qubits is studied. Going beyond the second order perturbation expansion, we find a time dependent…
