Scientists Achieve Successful Quantum Teleportation | Digital Trends Spanish
The quantum internet is called to mark a new era of communication. This network is made up of a group of protocols and systems that allow much more secure connections.
Thus, the quantum internet would be much faster and safer than the one we use today.
Everything indicates that we will not have to wait too long to start enjoying this technology, since a group of scientists from different institutions such as Fermilab, AT&T, Caltech, Harvard, NASA JPL and the University of Calgary has taken an important step in this area. .
Professionals have demonstrated sustained and highly accurate quantum teleportation over long distances.
The team was able to send information more than 44 kilometers with a fidelity of more than 90 percent, which is a record of precision for this distance.
“We are delighted with these results,” Fermilab scientists said in a statement.
“This is a key achievement on the path to building a technology that will redefine the way we conduct global communication.”
What does it consist of?
A qubit is similar to a bit, but in quantum computing it is considered the fundamental unit of the computing and technological future.
Quantum teleportation of a qubit (or quantum bit) is achieved through quantum entanglement, in which two or more particles are closely entangled with each other.
If a pair of entangled particles is shared between two separate locations, regardless of the distance that separates them, the encoded information is teleported.
Albert Einstein considered quantum teleportation “a frightening action at a distance”, since it violated relativity by traveling faster than the speed of light. By what is understood the reaction of scientists after this successful demonstration.
“With this demonstration we are beginning to lay the groundwork for the construction of a quantum network in the Chicago area,” add the authors.
