LIGO Detector Characterization in the Second and Third Parts of the Fourth Observing Run
J. Glanzer, A. F. Helmling-Cornell, A. Calafat +244
LIGO detector characterization efforts enabled the confident detection of gravitational waves from hundreds of compact binary coalescences during the fourth observing run. Reliable…
A Quantum-Enhanced Feedback Oscillator
Hudson A. Loughlin, Daniel M. DeSantis, Nergis Mavalvala +1
Feedback oscillators, such as lasers and masers, serve as time references in modern computing, communication, and measurement. Quantum fluctuations ultimately limit their phase sta…
Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run
E. Goetz, A. Neunzert, A. M. Knee +260
We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…
A Wafer-Scale Heterogeneous III-V-on-Silicon Nitride Quantum Photonic Platform
Lillian Thiel, Boqiang Shen, Jasper R. Venneberg +22
Heterogeneous integration of gain and strongly nonlinear materials with ultra-low-loss silicon nitride (SiN) photonics offers a route to scalable quantum circuits, but concurrent w…
Noise-Resilient Quantum Metrology
Hudson A. Loughlin, Melissa A. Guidry, Jacques Ding +7
Quantum metrology seeks to leverage the richness of quantum systems for making better measurements than are possible using only classical resources in order to gain a ``quantum adv…
50-km fiber interferometer for testing gravitational signatures in quantum interference
Haocun Yu, Dorotea Macri, Thomas Morling +10
Quantum mechanics and general relativity are the foundational pillars of modern physics, yet experimental tests that combine the two frameworks remain rare. Measuring optical phase…
