Must be your adblocker. It’s accessible to me in holland.

Able to read it with adblocker active while in France (on mobile).
> A team of researchers in China sent a photon from the ground to an orbiting satellite more than 300 miles above through a process known as quantum entanglement, according to MIT Technology Review. It’s the farthest distance tested so far in teleportation experiments, the researchers said. Their work was published online on the open access site arXiv.
> For about a month, the scientists beamed up millions of photons from their ground station in Tibet to the low-orbiting satellite. They were successful in more than 900 cases.

“A team of researchers in China sent a photon from the ground to an orbiting satellite more than 300 miles above through a process known as quantum entanglement”

imo, it’s far-fetched to call a photon an “object”.

#7no, they didn't; but they did redefine the definition of teleportation.

if they teleported anything, it was information, not matter or energy.

Aren't matter and energy just a manifestation of information though?

Well, it'll work once we figure out how to convert an atom or molecule into a photon and back.

I'm not sure if abstract semantics are a good place for scientific discovery announcement headlines.
