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…
Reinforcement Learning for Fast and Robust Longitudinal Qubit Readout
Yiming Yu, Yuan Qiu, Xinyu Zhao +2
Longitudinal coupling offers a compelling pathway for quantum nondemolition (QND) readout, but pulse design is constrained by hardware limitations such as the coupling strength and…
Enhancing light-matter coupling for exploring chaos in the quantum Rabi model
Yan-Song Hu, Yuan Qiu, Ye-Hong Chen +2
Accessing chaos in the quantum Rabi model (QRM) usually requires operating far from resonance, combined with ultra- or deep-strong light-matter coupling. This makes direct experime…
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…
