Simultaneous Speedmeter and Position-Meter Response in a Single Tabletop Interferometer
Mikhail Korobko, Xiang Li, Torben Sobottke +3
Quantum radiation-pressure noise (QRPN) limits the low-frequency sensitivity of gravitational wave detectors. The established method for suppressing QRPN is the injection of freque…
Boosting the sensitivity of high frequency gravitational wave detectors by PT-symmetry
Chuming Wang, Chunnong Zhao, Xiang Li +4
The kilo-Hertz gravitational waves radiated by the neutron star merger remnants carry rich information about the physics of high-density nuclear matter states, and many important a…
Scalable Simulation of Quantum Measurement Process with Quantum Computers
Meng-Jun Hu, Yanbei Chen, Yiqiu Ma +4
Recent development in quantum information sciences and technologies, especially building programmable quantum computers, provide us new opportunities to study fundamental aspects o…
Designing optimal linear detectors -- a bottom-up approach
Joe Bentley, Hendra Nurdin, Yanbei Chen +2
This paper develops a systematic approach to realising linear detectors with an optimised sensitivity, allowing for the detection of extremely weak signals. First, general constrai…
Angular emission patterns of remnant black holes
Xiang Li, Ling Sun, Rico Ka Lok Lo +2
The gravitational radiation from the ringdown of a binary black hole merger is described by the solution of the Teukolsky equation, which predicts both the temporal dependence and…
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…
