Didn't they already try that ? Engineers at Northwestern University have achieved quantum teleportation using fiber optic cables already carrying internet traffic. This milestone could simplify the path to secure quantum networks by leveraging existing infrastructure. Imagine two entangled particles created in a laboratory and then separated, with one particle sent to Location A and the other to Location B. When a specific property, such as polarization or spin, is measured on the particle at Location A, the corresponding property of the particle at Location B is instantly known. This connection occurs regardless of the physical distance between the particles, whether they are a few meters or light-years apart.
