Record for quantum teleportation broken in eight days

ananyo writes "Back in May, slashdot reported on the achievement of Chinese physicists who successfully teleported photonic qubits (quantum bits) over a distance of 97 kilometers. That distance surpassed the previous record, set by a group that included several of the same researchers, of 16 kilometers.
Now it has come to light that their new record was broken just eight days later by a European and Canadian group that claims to have teleported information from one of the Canary Islands to another, 143 kilometers away. They posted their paper to the preprint server ArXiv on May 17, while the Chinese group posted theirs on the same site on May 9."
