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 ...

Measurement-based linear optics implements a huge multi-mode interferometer consisting of beamsplitters (green) and phase delays (blue). The size of the virtual interferometer can be many hundreds or ...

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 ...

The quantification of large optics demands metrology systems that operate in the context of turbulence, vibration and additional challenges. Figure 1. Measurement of large optics, such as this 8-meter ...

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 ...
