What if, photons do interact?
The team believes that photon interactions could be manipulated in ways that make them an asset to quantum computers.
Until just a few years ago, scientists had never seen photons interact. In a new study, photons were observed binding in groups of three, accumulating mass, and slowing down.
Researchers observed groups of three photons not only interacting, but effectively combining to form a completely new type of photonic matter. This outcome essentially reveals a new form of light.
To make interacting photons, the team shone a weak laser through a cloud of cold rubidium atoms. Rather than emerging from this cloud separately, the photons within the laser merged bound in groups of three. This observation suggests a form of interaction and attraction — also known as entanglement.
