The NASA achieved the quantum teleportation Long distance? A Internet Viable quantum, a network in which information stored in qubits is shared over long distances through entanglement, would usher in a new era of communication.
The scientists of Fermi Lab., together with partners from five institutions, they have taken an important step towards implementing one Quantum internet.
In an article published in PRX Quantum, the team presents a demonstration of sustained teleportation for the first time. and long-range qubits made of photons (light particles) with greater than 90% reliability. The qubits they were teleported through a 44 kilometer fiber optic network using state-of-the-art single-photon detectors and ready-to-use equipment.
“We are very pleased with these results,” says the scientist Fermilab Panagiotis Spentzouris, director of the quantum science program Fermilab and one of the co-authors of the paper.
“This is a significant achievement towards building a technology that will redefine the way we conduct global communications.”
The achievement comes just months after the US Department of Energy. unveiled its plan for a national quantum internet at a press conference at the University of Chicago.
The quantum teleportation it is a “disembodied” transfer of quantum states from one place to another. Quantum teleportation of a qubit is achieved by quantum entanglement, where two or more particles are inseparably linked. If a pair of entangled particles are shared between two separate locations, regardless of the distance between them, the encoded information is teleported.
“With this demonstration, we begin to lay the foundation for the construction of a metropolitan quantum network in the Chicago area, ”said Spentzouris.
