Entanglement That Can't Be Broken: Photons in Invulnerable Quantum Communication ⚡ экспресс
Original: "Demonstration of unpartible entanglement"
For the first time, scientists have created quantum entanglement that doesn't depend on the observation method.

Usually quantum entanglement is fragile: change the reference frame, and it vanishes. Physicists have for the first time created an 'eternal' link between photons that doesn't break under any transformations. This is a step toward ultra-secure quantum communication that can work even in noisy, untrusted channels.
🎯 Photon entanglement is already used for quantum key distribution: even if someone intercepts the signal, the entanglement instantly reveals the intrusion.
