“Eavesdropping on the Quantum Universe” –Amazing New Technology

Futurizonte Editor’s Note: Now that we are beginning to see and hear the quantum universe, perhaps we will also be able to see and hear the universe inside us. Perhaps they are one and the same.

FROM THE ARTICLE:

Since the historic finding of gravitational waves from two black holes colliding over a billion light years away was made in 2015, physicists are advancing knowledge about the limits on the precision of the measurements that will help improve the next generation of LIGO tools and technology used by gravitational wave scientists.

Louisiana State University Department of Physics & Astronomy Associate Professor Thomas Corbitt and his team of researchers have created the first broadband, off-resonance measurement of quantum radiation pressure noise in the audio band, at frequencies relevant to gravitational wave detectors, as reported today in the journal Nature

The research was supported by the National Science Foundation, or NSF, and the results hint at methods to improve the sensitivity of gravitational-wave detectors by developing techniques to mitigate the imprecision in measurements called “back action,” thus increasing the chances of detecting gravitational waves.

Corbitt and researchers have developed physical devices that make it possible to observe–and hear–quantum effects at room temperature.

“Given the imperative for more sensitive gravitational wave detectors, it is important to study the effects of quantum radiation pressure noise in a system similar to Advanced LIGO, which will be limited by quantum radiation pressure noise across a wide range of frequencies far from the mechanical resonance frequency of the test mass suspension.”
