Catching a gravity wave in a tangle of photons

A quantum “ruler” could reveal gravitational waves fainter than we can now hope to detect. Gravitational waves are ripples in the fabric of space-time that physicists are trying to detect with interferometers – devices that split a beam of light into two and then recombine them to create interference fringes. A gravity wave passing through the device would change the distance travelled by one beam relative to the other, and this effect would show up as a change in the interference fringes. Current designs, though,
