Imaging Stars at the Quantum Compatibility Limit
Xinyao Guo, Haixing Miao, Zheng Cai +1
Imaging astrophysical sources with a multi-station interferometer is intrinsically a multiparameter quantum-estimation problem. {Using tools from multiparameter quantum metrology,}…

Experiment demonstration of tilt-to-length coupling suppression by beam-alignment-mechanism
Peng Qiu, Xiang Lin, Yurong Liang +3
Tilt-to-length (TTL) noise, caused by angular jitter and misalignment, is a major noise source in the inter-satellite interferometer for gravitational wave detection. However, the…
