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…
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…
Non-Markovian environment induced Schrödinger cat state transfer in an optical Newton's cradle
Xinyu Zhao, Yan Xia
In this manuscript, we study the Schrödinger cat state transfer in a quantum optical version of Newton's cradle in non-Markovian environment. Based on a non-Markovian master equat…
Non-Markovian environment induced chaos in optomechanical system
You-Lin Xiang, Xinyu Zhao, Yan Xia
In traditional research, chaos is frequently accompanied by non-linearity, which typically stems from non-linear interactions or external driving forces. However, in this paper, we…
Entanglement protection induced by mixed noise
Tengtao Guo, Yuxuan Zhou, Jiahui Feng +2
Contrary to the conventional view that noise is detrimental, we show that mixed noise can protect entanglement in a two-atom-cavity system. Specifically, the leakage of the cavity…
