Large Hadron Collider turned into world’s biggest quantum entanglement experiment

The Large Hadron Collider (LHC) is best known for smashing particles together at high speed, but now this huge machine has been used for a more delicate experiment – investigating quantum entanglement. The results, demonstrating entanglement between two subatomic particles called quarks, are the first of new efforts to test whether strange quantum phenomena can occur at extremely high energy levels, and could reveal new insights into the fundamental nature of reality.

Entanglement is a strange quantum effect where objects or particles are …
