Thermal Noise Measurement Below the Standard Quantum Limit
Ronald Pagano, Scott Aronson, Torrey Cullen +2
We present a method characterizing thermal noise in an optical cavity independent from quantum noise despite the thermal noise falling below the quantum noise limit. Using this met…

Optical Spring Tracking for Enhancing Quantum-Limited Interferometers
Scott Aronson, Ronald Pagano, Torrey Cullen +2
Modern interferometers such as LIGO have achieved sensitivities limited by quantum noise, comprised of radiation pressure and shot noise. To mitigate this noise, a static system is…

Photon Counting Interferometry to Detect Geontropic Space-Time Fluctuations with GQuEST
Sander M. Vermeulen, Torrey Cullen, Daniel Grass +8
The GQuEST (Gravity from the Quantum Entanglement of Space-Time) experiment uses tabletop-scale Michelson laser interferometers to probe for fluctuations in space-time. We present…
