A state-of-the-art experiment at the US Department of Energy’s (DoE) Fermi National Accelerator Laboratory ...

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 ...

Atom interferometry has emerged as a transformative approach in both fundamental physics and practical applications, utilising the wave nature of atoms to measure minute effects of gravity, rotation ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. "Reaching this milestone was incredibly challenging, and our success was not always a given," ...

Extremely precise measurements are possible using atom interferometers that employ the wave character of atoms for this purpose. They can thus be used, for example, to measure the gravitational field ...

NASA’s Cold Atom Lab, shown where it’s installed aboard the International Space Station, recently demonstrated the use of a tool called an atom interferometer that can precisely measure gravity and ...

For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the technology of ...

A new type of atom interferometer built by researchers at the University of Colorado (UC) Boulder measures acceleration in three dimensions (3D). Prior to this, acceleration was always measured in one ...

Toward the development of a “quantum compass” for navigation when GPS signal unavailable. Sandia scientists prepare a rubidium cold-atom cell for an interferometry experiment. Scientists are ...
