LIGO operates with quantum noise below the Standard Quantum Limit

Kavli Affiliate: Richard Mittleman | First 5 Authors: Wenxuan Jia, Victoria Xu, Kevin Kuns, Masayuki Nakano, Lisa Barsotti | Summary: 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 limitations imposed by quantum mechanics. The Heisenberg uncertainty principle dictates that […]

Stochastic waveform estimation at the fundamental quantum limit

Kavli Affiliate: Lee McCuller | First 5 Authors: James W. Gardner, Tuvia Gefen, Simon A. Haine, Joseph J. Hope, John Preskill | Summary: Although measuring the deterministic waveform of a weak classical force is a well-studied problem, estimating a random waveform, such as the spectral density of a stochastic signal field, is much less well-understood […]
