Researchers created quantum entanglement between two quantum systems at a 12,5 km distance.

Researchers created quantum entanglement between two quantum systems at a 12,5 km distance. The ability to exchange information between two memory systems is the base requirement for communication. When two persons are talking to each other they are exchanging information.

Or otherwise, we can say that their brains exchange information. And the human brain is one version of the memory system. When we are discussing, we share information. Sharing information requires certain protocols. And one of those protocols is biz talk. Another system that can be human or computer asks permission to use another system's databases. 

When an elder person gives pieces of advice the situation is the same as when a server offers a client access to its databases. In both cases, systems offer a path to information, stored in their memories. So when another person offers pieces of advice that means the person offers information to another person. 

During that process, we are transferring information through the air to another person. And we cannot share any other information. If we want to share information we must have it. That means information is stored in our memory or we cannot share it. All information that we get goes through memory. And if memory doesn't save that information. That information does not exist. 

When researchers are sending information through the air the requirement is that two information or memory systems are at the same frequency. So before researchers can create quantum entanglement over long distances they must send the information parameters to the receiver. Or receiver can send a message about what atom, ion, or particle group the sender must use. 

The ability to create long-range quantum entanglement and exchange information over 10 km is one of the most powerful things in quantum technology. If we want to create the ultra-secure quantum system that allows high-secure communication between two memory systems. We must realize that the thing that makes this type of communication difficult is that another quantum system must be at a higher energy level. 

The quantum information system can make it possible to create the WARP-speed communication tool. In that system, the quantum entanglement is created through the air by using a hollow maser or laser ray as the virtual cable that protects the quantum entanglement. 

The radiation channel around the quantum entanglement makes it hard to see changes in the energy level of that entanglement from outside. Also, that energy channel or synthetic- or electromagnetic wormhole protects the quantum entanglement from outside electromagnetic effects. The quantum entanglement is like the stick that is connecting two places. So information that travels in this kind of system at goal before the free-flying photon is. 

The benefits of this type of communication are increasing when the distance between sender and receiver grows. And that means the WARP speed communication is the most effective in the longest possible distances. If we want to make WARP-speed communication at a distance of a couple of kilometers the speed of the communication is not the top reason. 

The WARP speed communication is very hard to break and that thing means that data security is top of the ranking list when researchers create this kind of system. But if we would create that quantum communication line to Mars that allows real-time communication between Mars-rovers and ground stations.
