Researchers at Louisiana State University have invented an optical sensor that surpasses a quantum limit to sensitivity previously believed to be unbeatable. The breakthrough has a broad array of applications, from gravity wave observatories seeking to observe distant and bizarre astrophysical phenomena, to optical gyroscopes used in commercial navigation.
One would think that this would be highly applicable for detecting unusual objects flying around in our skies as well. To read the rest of the article, click here.
