Photonic matter is a state of matter in which photons behave as if they had mass, and can interact with each other, even forming photonic "molecules". This is in contrast to the usual properties of photons, which have no rest mass, and cannot interact.

Description

Photonic matter is achieved by "dispersive coupling of light to strongly interacting atoms in highly excited Rydberg states". The coupling is caused by a process called Rydberg blockade, where excitations caused by one photon constrain the interactions with the surrounding atoms available to the other photon, leading in effect to an interaction between the photons.

Applications

As of 2013, photonic matter is hypothesized to lend itself to applications in quantum computing and classical computing, and to the creation of strongly correlated states of light, possibly in the form of three-dimensional structures consisting only of light.

History

Photonic matter was first created in a laboratory in 2013.
