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…

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…

Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit
Wenxuan Jia, Victoria Xu, Kevin Kuns +168
Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental…
