Rapid and robust laser-frequency auto-locking using Bayesian-optimization and discrete-wavelet-transformation algorithms
Min Jiang, Xiao-Li Chen, Si-Bin Lu +8
Rapid and robust laser-frequency auto-locking is essential for the field deployment of quantum communications, quantum computing, and precision-measurement technologies; however, a…
Restoring Velocity Immunity via Dynamic Mirror Compensation in a Large-Area Dual-Atom-Interferometer Gyroscope
Jie Gu, Yin-fei Mao, Zhan-Wei Yao +10
We propose and demonstrate a dynamical mirror compensation scheme to restore velocity immunity in a large-area dual-atom-interferometer gyroscope. In an ideal Mach-Zehnder configur…
Amplitude Modulation Noise Suppression of Dynamic Atom Gravimeters
Wen-Zhang Wang, Jin-Ting Li, Dan-Fang Zhang +9
Dynamic atom gravimeters enable absolute gravity measurements on moving platforms. However, their performance is severely degraded due to the complex dynamic environment. This pape…
In-orbit Test of the Weak Equivalence Principle with Atom Interferometry
Dan-Fang Zhang, Jing-Ting Li, Wen-Zhang Wang +22
The Weak Equivalence Principle (WEP) is a central pillar of general relativity. Its precise test with quantum systems in space offers a unique window onto new physics. Here we repo…
Highly stable modular-assembled laser system for a dual-atom-interferometer gyroscope
Chuan Sun, Si-Bin Lu, Min Jiang +8
Operating atom-interferometer gyroscopes outside a laboratory environment is challenging primarily owing to the instability of laser systems. To enhance the thermal stability of fr…
