Dec. 31 (UPI) — For the first time, scientists successfully demonstrated sustained, long-distance teleportation of quantum information.
The breakthrough, described this month in the journal PRX Quantum, suggests a viable quantum internet could soon be a reality.
“Quantum teleportation is essential for many quantum information technologies, including long-distance quantum networks,” according to the study’s authors.
Quantum teleportation is made possible by the quantum phenomenon known as entanglement, which describes two inextricably linked particles, whereby the measure or manipulation of one particle is observed in the other, regardless of time or location.
In the first-of-its-kind demonstration, researchers at the Fermi National Accelerator Laboratory, a U.S. Department of Energy national laboratory affiliated with the University of Chicago, successfully teleported quantum information, or qubits, over a fiber-optic network stretching 27 miles.
Researchers actually tested their quantum teleportation technology on two different networks: the Caltech Quantum Network and the Fermilab Quantum Network.
During their trips across the two networks, built using a combination of commercial equipment and state-of-the-art single-photon detectors, the teleported photon particles maintained their fidelity at a rate of 90 percent.
