University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

Researchers have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where background noise and optical loss from the sample are present. (Nanowerk News) ...

Currently, quantum photon sources are regularly taken offline to be tested and adjusted using an interferometer. This requires comparing photons multiple times using different configurations, a ...

A team of researchers from France has developed the first three-directional hybrid quantum inertial sensor, which can measure acceleration without using satellite signals. At the heart of this ...

For astronomers, one of the greatest challenges is capturing images of objects and phenomena that are difficult to see using optical (or visible light) telescopes. This problem has been largely ...

The figure shows how atoms with opposing spins are separated into two streams using magnets and then brought back together, creating an interference pattern. If any external quantum processes affect ...
