Programmable spectral symmetries in an anisotropic quantum Rabi simulator
Jia-Cheng Song, Yu Liu, Ming-Chuan Wang +28
The quantum Rabi model captures fundamental aspects of light--matter interaction, where symmetry dictates both spectra and dynamics. Over the past years, experiments have explored…
Demonstration of High-Fidelity Gates in a Strongly Anharmonic with Long-Coherence C-Shunt Flux Qubit
Silu Zhao, Li Li, Weiping Yuan +13
We demonstrate high-fidelity single-qubit gates on a C-shunt flux qubit that simultaneously combines a large anharmonicity () with long relaxation…
Stable and Efficient Charging of Superconducting Capacitively Shunted Flux Quantum Batteries
Li Li, Si-Lu Zhao, Yun-Hao Shi +15
Quantum batteries, as miniature energy storage devices, have sparked significant research interest in recent years. However, achieving rapid and stable energy transfer in quantum b…
Experimental Extraction of Coherent Ergotropy and Its Energetic Cost in a Superconducting Qubit
Li Li, Silu Zhao, Yun-Hao Shi +4
Quantum coherence, encoded in the off-diagonal elements of a system's density matrix, is a key resource in quantum thermodynamics, fundamentally limiting the maximum extractable wo…
Many-body delocalization with a two-dimensional 70-qubit superconducting quantum simulator
Tian-Ming Li, Zheng-Hang Sun, Yun-Hao Shi +35
Quantum many-body systems with sufficiently strong disorder can exhibit a non-equilibrium phenomenon, known as the many-body localization (MBL), which is distinct from conventional…
Quantum Acoustics with Superconducting Qubits in the Multimode Transition-Coupling Regime
Li Li, Xinhui Ruan, Si-Lu Zhao +23
Hybrid mechanical-superconducting systems for quantum information processing have attracted significant attention due to their potential applications. In such systems, the weak cou…
