The 6G communication can use terahertz radiation.

"Tohoku University researchers have developed a tunable filter for terahertz wave signals, facilitating higher transmission rates and improved signal quality. This breakthrough, crucial for the advancement of terahertz applications in communication, medical imaging, and industrial analysis, promises to unlock the full potential of terahertz waves across various fields." (ScitechDaily, Unlocking the Future of 6G: A New Breakthrough in Terahertz Communication) The world is going to be mobile. And that means there is always a need for new and faster mobile networks. The problem with data networks is that even if 4G and 5G are fast. Mobile applications always turn harder and harder. More and more mobile applications like cell phones connect to mobile networks. And that thing increases the need for data transportation capacity.  In the future, all TV sets and even houses use wireless data transmission because data cables are expensive. It's cheaper and easier to install long-r

Quantum networks can make the world more secure.

And that is the next step for ultra-secured data transmission. The networks are unable to operate if they are not secured. The cornerstone for secure communication is that the systems can exchange keys securely.  The neurocomputer requires ultra-secure communication.  The new findings are a big advantage to developing quantum networks.  The difference between quantum networks and regular networks is that in quantum networks, information travels in qubits. The quantum network's problem is that the system packs information in the physical object. And that makes quantum computers resistant to regular eavesdropping.  However, the quantum computer i
