The breakthrough, described this month in the journal PRX Quantum, suggests a viable quantum internet could soon be a reality. Advertisement "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.
