Quantum light may help retrieve entanglement from strange metals

Quantum entanglement remains one of physics’ strangest ideas. Two particles become linked so closely that changing one instantly affects the other, even across large distances. Scientists have studied this effect for years in tiny quantum systems, but controlling it in larger materials has proved much harder. Researchers at Rice University believe they may have found a way to make that process easier. Physicist Qimiao Si and his collaborators ha…
