Quantum Teleportation Isn’t Just Science Fiction AnymoreBy Toby Tunwase
Teleportation in fiction is the on-the-spot travel of objects between two locations without crossing a spatial barrier. But this is not just fiction anymore. Recent studies have been working to bring teleportation-like technologies into our reality.
This concept of teleportation can be used on the quantum level to prevent loss in communication channels. The technique of quantum teleportation involves teleporting information rather than matter.
Loss of communication that occurs across various channels such as phones or the internet can be reduced via this mechanism according to a team of researchers from the Center for Quantum Dynamics at Griffith University.
Researchers from the National Institute of Standards and Technology and the University of Queensland spoke about the importance of such findings. Although it sounds like science fiction, quantum internet is a possible technology we’ll see in the future.
According to the study carried out by these researchers, quantum technologies can revolutionize our society as it is the first to show an error reduction technique that significantly enhances the performance of a channel. It thrives on information and help transmit data in a way that’s completely secure and safe such that it becomes inaccessible to a third party.
Quantum encryption for short distance is currently being used commercially but deploying this on a global scale faces certain unavoidable issues such as photon loss. It is therefore important to devise a channel or mechanism for long-distance quantum communication that has minimal to no information loss. Following that, eliminating errors will open opportunities for long-distance quantum cryptography.
