A team of scientists has developed a novel way to measure variations in the Earth's rotation. In their paper published in the journal Nature Photonics, the team explains how their new approach works and how well it did when ...
It is possible to image an object with an induced coherence effect by making use of photon pairs to gain information on the item of interest—without detecting the light probing it. While one photon illuminates the object, ...
Scientists with the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers said the method demonstrates great promise; the dots are already as efficient as existing ...
