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,}…
Torsional-X Seismometer for Lunar Decihertz Gravitational-Wave Detection
Yulin Xia, Denis Martynov, Huan Yang +1
The lunar gravitational-wave antenna concept uses the Moon as a resonant detector instrumented with precision seismometers, targeting the decihertz band between ground- and space-b…
Beijing Normal University 12-meter Interferometric kHz GW Detector Prototype: Design and Scientific Prospects
Mengyao Wang, Fan Zhang, Xinyao Guo +17
Current gravitational-wave detectors have achieved remarkable sensitivity around 100 Hz, enabling ground-breaking discoveries. Enhancing sensitivity at higher frequencies in the ki…
Fundamental quantum limits for detecting ultrahigh frequency gravitational waves
Xinyao Guo, Haixing Miao, Zhi-Wei Wang +2
The ultrahigh-frequency (above 10 kHz) gravitational waves (GW) window provides a unique opportunity to detect primordial GWs, free from astrophysical foregrounds that dominate low…
