Physicists 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 of atoms.

This collage highlights several concepts proposed by 2024 NIAC Phase I awardees, including miniaturized interstellar spacecraft, a Venus glider, a water detoxifier for Mars, a solar-system-scale ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

If you want to get the greatest benefit from a beam of light - whether to detect a distant planet or remedy an aberration in the human eye - you need to be able to measure its beam front information.

Hard X-ray phase-contrast imaging characterizes the electron density distribution in an object without the need for radiation absorption. The power of phase contrast to resolve subtle changes, such as ...

Who’s who: The quantum Alice in Wonderland would like to understand whether the many “Twindeldum-Twindeldees” she sees are really identical or not, and uses the new interferometer for this purpose.

Particle-wave duality enables the construction of interferometers for matter waves, which complement optical interferometers in precision measurement devices. This requires the development of ...

The AIMS Interferometer represents over 20 years leading edge development resulting in easy to use, robust products, which have been specifically optimised for each measurement application. All ...
