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…
Neural Network-Based Design of Approximate Gottesman-Kitaev-Preskill Code
Yexiong Zeng, Wei Qin, Ye-Hong Chen +2
Gottesman-Kitaev-Preskill (GKP) encoding holds promise for continuous-variable fault-tolerant quantum computing. While an ideal GKP encoding is abstract and impractical due to its…
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…
Quantum amplification and simulation of strong and ultrastrong coupling of light and matter
Wei Qin, Anton Frisk Kockum, Carlos Sánchez Muñoz +2
The interaction of light and matter at the single-photon level is of central importance in various fields of physics, including, e.g., condensed matter physics, astronomy, quantum…
