The record for furthest distance for quantum teleportation over a a normal metropolitan fiber optic cable has been broken setting the new record at 7 kilometers. the record for quantum teleportation through empty space.
What is quantum teleportation?
Quantum teleportation is the sending of information instantaneously between two entangled particles. The information sent does not physically travel from one point to another. Information can be transmitted because one entangled particle will copy the state of the other one regardless of distance.
What is the point of using quantum teleportation?
Using quantum teleportation to send information has many benefits in speed and security. Information is sent instantaneously meaning it can be used for instant communication no matter the distance. The lack of a physical carrier of information from point A to point B makes it difficult to intercept information sent.
