(Independent.uk) Quantum teleportation – sending qubits of photons through a fiber-optic cable – has been demonstrated for the first time by researchers from Fermilab, AT&T, Caltech, Harvard University, Nasa’s Jet Propulsion Laboratory and the University of Calgary.
The achievement could be used to develop a quantum internet service, which would revolutionise data storage and computing; scientists also claim it will usher in a new era of communication.
Scientists sent qubits through 44 kilometers of fiber-optic network with a 90 per cent degree of fidelity. This network was built with off-the-shelf equipment, which would be compatible with existing internet infrastructure. “We wanted to push the envelope for this type of research and take important steps on a path to realise both real-life applications for quantum communications and networks and test fundamental physics ideas,” Panagiotis Spentzouris, head of the Quantum Science Program at Fermilab.
“People on social media are asking if they should sign up for a quantum internet provider (jokingly of course),” Maria Spiropulu, Shang-Yi Ch’en professor of physics at Caltech, said. “We need (a lot) more R&D work.”
