Wave--particle transition and quantum Zeno effect in which-way experiments with a superconducting quantum processor
Shiyu Wang, Zhiguang Yan, Clemens Gneiting +3
Wave--particle duality demonstrates the peculiar nature of quantum mechanics. In which-way experiments, depending on the measurement scheme, a particle exhibits either wave-like or…
Resonance fluorescence of an artificial atom with a time-delayed coherent feedback
Ching-Yeh Chen, Gavin Crowder, Zheng-Qi Niu +7
The model of light-matter interaction in quantum electrodynamics typically relies on the Markovian approximation, which assumes that the system's future evolution depends solely on…
Probing strongly driven and strongly coupled superconducting qubit-resonator system
Oleh V. Ivakhnenko, Christoforus Dimas Satrya, Yu-Cheng Chang +5
We investigated a strongly driven qubit strongly connected to a quantum resonator. The measured system was a superconducting flux qubit coupled to a coplanar-waveguide resonator wh…
Engineering the Environment of a Superconducting Qubit with an Artificial Giant Atom
Jingjing Hu, Dengfeng Li, Yufan Qie +4
In quantum computing, precise control of system-environment coupling is essential for high-fidelity gates, measurements, and networking. We present an architecture that employs an…
