Part 4/7:
Another critical phenomenon supporting the quantum internet is entanglement. When two quantum particles become entangled, the state of one particle can provide insights into the state of the other, regardless of the distance separating them. This instantaneous connection can facilitate near-instant communication over vast distances, potentially faster than light itself.
However, transmitting entangled particles introduces practical challenges. Even after establishing entanglement, moving these particles to their respective destinations remains problematic. Current solutions still rely on fiber optic cables, which face issues such as scattering or absorption of photons during transmission.
