Physicists from University of Bristol managed to teleport data between two chips using quantum entanglement. It is a big achievement; this move could help ‘protect the world’s data’ on superfast quantum computers.
In other words, research team managed to send information from one chip to another instantly not by any physical or electronic connection. This achievement opens the door for quantum computers and quantum internet.
Quantum entanglement:
Scientists made this teleportation possible by a phenomenon called quantum entanglement. In this phenomenon, two particles get entangled with each other. They can “communicate”, even if they’re miles apart. If you change the properties of one particle, it will cause the other to instantly change too, irrespective of the space between two of them. In essence, information is being teleported between them.
“We were able to demonstrate a high-quality entanglement link across two chips in the lab, where photons on either chip share a single quantum state,” says Dan Llewellyn, co-author of the study.
“Each chip was then fully programmed to perform a range of demonstrations which utilize the entanglement. The flagship demonstration was a two-chip teleportation experiment, whereby the individual quantum state of a particle is transmitted across the two chips after a quantum measurement is performed. This measurement utilizes the strange behavior of quantum physics, which simultaneously collapses the entanglement link and transfers the particle state to another particle already on the receiver chip.”
This could lead to the creation of a new secure ‘quantum internet’
According to researchers, this study could lead to a quantum internet that ‘would ultimately protect the world’s information from malicious attacks’.
