MEMS vapor cells-based Rydberg-atom electrometry toward miniaturization and high sensitivity

Yintao Ma, Yao Chen, Yanbin Wang, Ju Feng Guo et autres

Rydberg-atom electrometry, as an emerging cutting-edge technology, features high sensitivity, broad bandwidth, calibration-free operation, and beyond. However, until now the key atomic vapor cells used for confining electric field-sensitive Rydberg atoms nearly made with traditional glass-blown techniques, hindering the miniaturization, integration, and …

Do World Action Models Generalize Better than VLAs? A Robustness Study

Zhanguang Zhang, Zhiyuan Li, Behnam Rahmati, Rui Heng Yang et autres

Robot action planning in the real world is challenging as it requires not only understanding the current state of the environment but also predicting how it will evolve in response to actions. Vision-language-action (VLA), which repurpose large-scale vision-language models for robot action …

WALDO: Where Unseen Model-based 6D Pose Estimation Meets Occlusion

Sajjad Pakdamansavoji, Yintao Ma, Amir Rasouli, T. Cao

Accurate 6D object pose estimation is vital for robotics, augmented reality, and scene understanding. For seen objects, high accuracy is often attainable via per-object fine-tuning but generalizing to unseen objects remains a challenge. To address this problem, past arts assume access to …

Theoretical study on rotation measurement with quantum vibration oscillators based on ion crystal in a Penning trap

Yao Chen, Ruyang Guo, Ju Guo, Yintao Ma et autres

In traditional mechanics, harmonic oscillators can be used to measure force, acceleration, or rotation. Herein, we describe a quantum harmonic oscillator based on a Penning-trapped calcium ion crystal. Similar to traditional oscillators, the Coriolis force-induced axial oscillation amplitude is precisely measured to …
