Dynamics and Resonance Fluorescence from a Superconducting Artificial Atom Doubly Driven by Quantized and Classical Fields
Xinhui Ruan, Jia-Heng Wang, Dong He +11
We report an experimental demonstration of resonance fluorescence in a two-level superconducting artificial atom under two driving fields coupled to a detuned cavity. One of the fi…

Two-dimensional topological effect in a transmon qubit array with tunable couplings
Yan-Jun Zhao, Yu-Qi Wang, Yang Xue +4
We investigate a square-lattice architecture of superconducting transmon qubits with inter-qubit interactions mediated by inductive couplers. Therein, the inductive couling between…
