Enhancing interferometer sensitivity without sacrificing bandwidth and stability: beyond single-mode and resolved-sideband approximation
Xiang Li, Jiri Smetana, Amit Singh Ubhi +5
Quantum noise limits the sensitivity of precision measurement devices, such as laser interferometer gravitational-wave observatories and axion detectors. In the shot-noise-limited…
Broadband sensitivity improvement via coherent quantum feedback with PT symmetry
Xiang Li, Maxim Goryachev, Yiqiu Ma +4
A conventional resonant detector is often subject to a trade-off between bandwidth and peak sensitivity that can be traced back to quantum Cramer-Rao Bound. Anomalous dispersion ha…
Linear quantum measurement theory of matter-wave interferometry
Yiqiu Ma, Xiang Li, Shengjun Yang +1
The theory of linear quantum measurement has been developed for analysing the sensitivities of experimental devices that measure extremely weak signals, such as gravitational waves…
Coherent coupling completes an unambiguous optomechanical classification framework
Xiang Li, Mikhail Korobko, Yiqiu Ma +2
In most optomechanical systems a movable mirror is a part of an optical cavity, and its oscillation modulates either the resonance frequency of the cavity, or its coupling to the e…
