Spin-Squeezing-Enhanced Charging for Quantum Dicke Batteries
Ke-Xiong Yan, Jia-Wen Yu, Yiming Yu +5
High-power Dicke quantum batteries (QBs) typically exploit collective superradiance, whereas intrinsic matter-matter interactions are conventionally considered detrimental. Here, w…
Qubit Readout via State-Dependent Radiative Linewidths
Yiming Yu, Xinyu Zhao, Jia-Wen Yu +5
Fast qubit readout conventionally encodes state information in a dispersive frequency shift. Here we formulate a linewidth-encoded quantum non-demolition measurement channel in whi…
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…
Anisotropic Rabi Model as a Noise Biased Qubit
Jia-Wen Yu, Ke-Xiong Yan, Yuan Qiu +7
We present the quantum anisotropic Rabi model as a potential resource for a noise biased qubit. The system-environment coupling can be biased by tuning the relative strengths of th…
Dissecting the superradiant phase transition in the anisotropic Rabi model: Pattern competition and cavity-QED simulation
Yuan Qiu, Ke-Xiong Yan, Jun-Hao Lin +3
In this manuscript, we analyze the mechanism of the superradiant phase transition in the anisotropic Rabi model under the classical oscillator limit using the pattern picture. By e…
Entanglement generation of arbitrary squeezed Fock states
Qin-Ru Cheng, Ke-Xiong Yan, Yuan Qiu +3
We propose an efficient and robust protocol for the generation of entanglement between a superconducting qubit and a squeezed cavity. By applying a parametric drive to the cavity c…
