The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

In the classical world, a beam of light is a smooth, continuous wave. In the quantum realm, however, photons manifest as the discrete constituents (quanta) of light. These photons can be carefully ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a superconducting material. The kind of light you use can reveal very different things ...
