Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, ...

Carbon nanotubes are moving from lab curiosities to workhorse components in quantum hardware, and one of the most striking examples is their use as single-photon light sources. By exploiting their ...

Everything on the electromagnetic spectrum has some properties of both waves and particles, but it’s difficult to imagine a ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...
