We demonstrate high-fidelity single-qubit gates on a C-shunt flux qubit that simultaneously combines a large anharmonicity () with long relaxation…
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…
Flexible Readout and Unconditional Reset for Superconducting Multi-Qubit Processors with Tunable Purcell Filters
Yong-Xi Xiao, Da'er Feng, Xu-Yang Gu +18
Achieving high-fidelity qubit readout and reset while preserving qubit coherence is essential for quantum error correction and other advanced quantum algorithms. Here, we design an…
Quantum Acoustics with Superconducting Qubits in the Multimode Transition-Coupling Regime
