The NASA got the quantum teleportation long distance? one Internet viable quantum, a network in which information stored in qubits is shared over long distances through interlacing, would give way to a new era of communication.
The scientists of the Fermi Lab., together with partners from five institutions, they have taken a significant step in the direction of carrying out one Quantum Internet.
In an article published in PRX Quantum, the team presents for the first time a demonstration of sustained teleportation and long-distance qubits made of photons (light particles) with a fidelity greater than 90%. the qubits they were teleported through a 44-kilometer-long fiber optic network using state-of-the-art single-photon detectors, as well as ready-to-use equipment.
“We are delighted with these results,” the scientist from the Fermilab Panagiotis Spentzouris, Director of the Quantum Science Program Fermilab and one of the co-authors of the article.
“This is a key success on the road to building a technology that will redefine the way we conduct global communication.”
The achievement comes just months after the US Department of Energy. announced his plan for a national quantum Internet at a press conference at the University of Chicago.
the quantum teleportation it is an “incorporeal” transfer of quantum states from one place to another. Quantum teleportation of a qubit is achieved by quantum entanglement, in which two or more particles are inextricably linked together. If a pair of intertwined particles is shared between two separate locations, regardless of the distance between them, the encoded information is teleported.
“With this demonstration we are beginning to lay the groundwork for the construction of a metropolitan quantum network in the Chicago area, ”Spentzouris said.
