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…
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…
Critical States Preparation With Deep Reinforcement Learning
Jia-Wen Yu, Yi-Ming Yu, Ke-Xiong Yan +4
The fast and efficient preparation of quantum critical states is a challenging yet crucial task for various quantum technologies. This difficulty is most particularly for systems n…
Relaxed parameter sensitivity for multiphoton quantum resonances
Hao-Lin Zhong, Ke-Xiong Yan, Yi-Ming Yu +4
Multiphoton resonances demonstrate the physical significance of counter-rotating wave terms in light-matter interactions. These resonances, however, are sensitive to detuning error…
Controllable Non-Hermitianity in Continuous-Variable Qubits
Ke-Xiong Yan, Zhi-Cheng Shi, Ye-Hong Chen +1
Pure dephasing is the dominant leak mechanism in photonic cat qubits because its phase errors disrupt the parity protection, rendering the qubit vulnerable to energy relaxation. In…
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…
Giant-Atom Quantum Batteries
Ke-Xiong Yan, Yang Liu, Yang Xiao +5
Environmentally induced decoherence poses a fundamental challenge to quantum energy storage systems, causing irreversible energy dissipation and performance aging of quantum batter…
Spontaneous emission in Casimir-Rabi oscillations through a weak optomechanical coupling
Ke-Xiong Yan, Yuan Qiu, Yang Xiao +3
The dynamical Casimir effect (DCE) describes the energy conversion from a mechanical motion to the electromagnetic fields. When the mechanical oscillator is in a mechanically excit…
Generating three-photon Rabi oscillations without a large-detuning condition
Ke-Xiong Yan, Yuan Qiu, Yang Xiao +2
It is well known that in the quantum Rabi model, a three-photon resonance occurs when the cavity field bare frequency is about 1/3 of the atomic transition frequency. In this manus…
Optimally robust shortcuts to population inversion in cat-state qubits
Shao-Wei Xu, Zhong-Zheng Zhang, Yue-Ying Guo +2
Cat-state qubits formed by photonic coherent states are a promising candidate for realizing fault-tolerant quantum computing. Such logic qubits have a biased noise channel that the…
