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.

A state-of-the-art experiment at the US Department of Energy’s (DoE) Fermi National Accelerator Laboratory is one step closer to collecting experimental data. Fermilab has announced that it has ...

A team of astronomers from the U.S. Naval Observatory (USNO), Naval Research Laboratory (NRL) and the European Southern Observatory (ESO) have successfully used the ultra high-resolution capability of ...

All in a spin: Two indistinguishable photons (red lines) are incident on a beamsplitter cube and become entangled. The two photons are then coupled into an optical fibre-based interferometer, which is ...

The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with visible light by ...
