"The theoretical discovery of the split photon—known as a “Majorana boson”—advances the fundamental understanding of light and how it behaves... Every photon can be thought of as the sum of two distinct halves... Rather than pieces that can be physically pulled apart, the photon halves are similar to the two sides of a coin... the Majorana boson could support quantum computing, optical sensors, and light amplifiers"
