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…
Quantum gyroscope based on the cavity magnomechanical system
Zhe-Qi Yang, Lei Chen, Yu-Rong Lin +2
High-precision rotational angle measurement in noise-prone environments holds critical impor tance in aerospace engineering, military navigation, and related domains. In this paper…
Imaginary-Stark Skin Effect
Heng Lin, Jinghui Pi, Yunyao Qi +3
A unique phenomenon in non-Hermitian systems is the non-Hermitian skin effect (NHSE), namely the boundary localization of continuous-spectrum eigenstates. However, studies on the N…
Exponentially Improved Dispersive Qubit Readout with Squeezed Light
Wei Qin, Adam Miranowicz, Franco Nori
It has been a long-standing goal to improve dispersive qubit readout with squeezed light. However, injected external squeezing (IES) {\it cannot} enable a practically interesting i…
