In a major breakthrough, a joint team of researchers from Caltech, the Fermilab, Department of Energy, AT&T, Harvard University, NASA’s Jet Propulsion Lab and the University of Calgary announced that she had successfully teleported photon qubits through about 43 kilometers (43.4523 kilometers) of fiber optic cable, by Fermilab.
Similar projects had been carried out in the past; however, this one stands out from the rest because it is the first to diffuse quantum information over such a great distance.
The experiment, carried out using “plug-and-play” equipment that is compatible with both existing telecommunications infrastructure and emerging quantum technologies, could “provide a realistic basis for a high-fidelity quantum internet with high-fidelity devices. practices, ”the researchers said. Motherboard.
The study was published in the journal Like PRX.
Revolutionizing data storage and computing
Scientists were able to send qubits, which work by replacing traditional bits with quantum bits, via 43 kilometers (43.4523 kilometers) of fiber optic cable with a network built with ready-to-use equipment. In addition, the researchers were able to experiment through two separate networks and with a loyalty greater than 90 percent.
Scientists say this achievement will usher in a new era of communication, for Independent. Once this achievement is used to develop a quantum Internet service, it could revolutionize data storage and computing.
According to the researchers, the team had worked with perseverance and “kept their heads down for the past few years.”
Panagiotis Spentzouris, manager of the quantum science program at Fermilab, wrote in an email to Motherboard, “We wanted to push the boundaries of this kind of research and take important steps towards realizing real applications for quantum communications and networks, and testing ideas in fundamental physics.

“So when we finally did it, the team was thrilled, very proud to have achieved these high quality and record results,” he explained. “And we are very happy to be able to move on to the next phase, using the know-how and technologies of this work for the deployment of quantum networks.”
Does that mean you should sign up with a quantum internet provider? Not really. Responding to questions jokingly posed on social media, Maria Spiropulu, Shang-Yi Ch’en physics professor at Caltech, said, “We need (a lot) more R&D work.”
