A single photon reveals quantum entanglement of 16 million atoms

Quantum theory predicts that a vast number of atoms can be entangled and intertwined by a very strong quantum relationship, even in a macroscopic structure. Until now, however, experimental evidence has been mostly lacking, although recent advances have shown the entanglement of 2,900 atoms. Scientists at the University of Geneva (UNIGE), Switzerland, recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimetre crystal. They have published their results in Nature Communications.

Cool. I asked a question on this very subject recently after watching a very interesting documentary on the same subject. I thought about the scope of entanglement.

I don’t doubt that they’re right. But if I was skeptical I’d say: “So a photon enters a crystal in a specific direction and leaves in the same direction – big deal”.
