Researchers suggest novel way to generate a light source made from entangled photons

Entanglement is a strange phenomenon in quantum physics where two particles are inherently connected to each other no matter the distance between them. When one is measured, the other measurement is instantly a given. Researchers from Purdue University have proposed a novel, unconventional approach to generate a special light source made up of entangled photons. On Sept. 6, 2022, they published their findings in Physical Review Research.
