Whether a beam of light passes through an object often depends on the material of the object and the properties of the light, such as its frequency, color, and polarization. These properties can be assigned to individual photons, but some characteristics of light emerge only collectively, through quantum correlations between many photons. Developing materials that
Whether a beam of light passes through an object often depends on the material of the object and the properties of the light, such as its frequency, color, and polarization. These properties can be assigned to individual photons, but some characteristics of light emerge only collectively, through quantum correlations between many photons. Developing materials that manipulate these collective properties has been a substantial challenge, but writing in NatureYou et al.1 report a nanostructured material that can filter light according to its “quantum statistics,” which describe how photon arrivals at detectors correlate with each other.
