Researchers at the Department of Energy’s Oak Ridge National Laboratory are paving the way for the future detection of dark ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely tuned laser experiment could, in principle, nudge gravitational waves ...

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.

The gravitational wave transmits an energy packet to the light wave. It should be feasible to observe both phenomena, namely, the stimulated emission and absorption of gravitons, although this would ...

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 ...
