AI Summary

Physicists have succeeded in measuring a previously unobserved form of quantum entanglement after a 25‑year effort. The new measurements confirm that entangled particles share a joint quantum identity, existing in superposition until one is measured, and that this connection operates across any distance. Researchers note that while the outcomes are random and cannot convey information, the result still demonstrates the non‑local nature of entanglement. The work expands experimental access to the “other” kind of entanglement predicted by the Standard Model, though it remains unrelated to gravity.
