Quantum communication could be an option for absolutely secure transfer of data. The key component in quantum communication over long distances is entanglement between two atomic systems. Entanglement is very fragile and until now researchers have only been able to maintain the entanglement for a fraction of a second. But researchers have now succeeded in maintaining the entanglement for up to an hour.
