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…
Fabrication and Characterization of Impedance-transformed Josephson Parametric Amplifier
Zhengyang Mei, Xiaohui Song, Xueyi Guo +10
In this paper, we introduce a method of using a double-layer resist lift-off process to prepare the capacitor dielectric layer for fabricating impedance-engineered Josephson parame…
On-demand shaped photon emission based on a parametrically modulated qubit
Xiang Li, Sheng-Yong Li, Si-Lu Zhao +13
In the circuit quantum electrodynamics architectures, to realize a long-range quantum network mediated by flying photon, it is necessary to shape the temporal profile of emitted ph…
Tunable coupling of a quantum phononic resonator to a transmon qubit with flip-chip architecture
Xinhui Ruan, Li Li, Guihan Liang +16
A hybrid system with tunable coupling between phonons and qubits shows great potential for advancing quantum information processing. In this work, we demonstrate strong and tunable…
