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 ...

Researchers propose an unconventional way to generate light made from entangled photons. In the graphic above, photons meet the electrons of a helium atom, which then emits two entangled photons.

Dark matter could be made up of ultralight dark photons that heated up our universe: this is a new scenario proposed in a study recently published in the scientific journal Physical Review Letters.
