This book presents a direct measurement of quantum back action, or
radiation pressure noise, on a macroscopic object at room
temperature across a broad bandwidth in the audio range. This noise
source was predicted to be a limitation for gravitational wave
interferometers in the 1980s, but it has evaded direct
characterization in the gravitational wave community due to the
inherent difficult of reducing thermal fluctuations below the
quantum back action level. This back action noise is a potential
limitation in Advanced LIGO and Advanced Virgo, and Cripe's
experiment has provided a platform for the demonstration of quantum
measurement techniques that will allow quantum radiation pressure
noise to be reduced in these detectors. The experimental techniques
Cripe developed for this purpose are also applicable to any
continuous measurement operating near the quantum limit, and could
lead to the possibility of observing non-classical behavior of
macroscopic objects.
