A viable quantum internet — a network in which information stored in qubits is shared over long distances through entanglement — would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication. This month, scientists at Fermilab, a U.S. Department of Energy Office of Science national laboratory, and their partners took a significant step in the direction of realizing a quantum internet. In a paper published in PRX Quantum, the team presents for the first time a demonstration of a sustained, long-distance (44 kilometers of fiber) teleport...

Researchers Demonstrate Sustained, Long-Distance Teleportation of Photon Qubits Written by AZoQuantumDec 16 2020 Precision sensing, data storage, and computing could be completely revolutionized by a viable quantum internet—a network where information stored in qubits is shared over long distances via entanglement—leading to a new communication era. In a demonstration of high-fidelity quantum teleportation at the Fermilab Quantum Network, fiber-optic cables connect off-the-shelf devices (shown above), as well as state-of-the-art R&D devices.
