Quantum information ‘teleported’ at Fermilab, Caltech represents step toward quantum internet Aviable 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 Fermi National Accelerator Laboratory—a U.S. Department of Energy national laboratory affiliated with the University of Chicago—along with partners at five institutions 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 teleportation of qubits made of photons (particles of light) with fidelity greater than 90%.
The qubits were teleported over a fiber-optic network 27 miles (44 kilometers) long using state-of-the-art single-photon detectors, as well as off-the-shelf equipment.
“We’re thrilled by these results,” said Fermilab scientist Panagiotis Spentzouris, head of the Fermilab quantum science program and one of the paper’s co-authors. “This is a key achievement on the way to building a technology that will redefine how we conduct global communication.”
The achievement comes just a few months after the U.S. Department of Energy unveiled its blueprint for a national quantum internet at a press conference at the University of Chicago.
