Scientists have successfully teleported an object from Earth to space for the first time, paving the way for more ambitious and futuristic breakthroughs.
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.
The MIT-owned magazine described quantum entanglement as a "strange phenomenon" that occurs "when two quantum objects, such as photons, form at the same instant and point in space and so share the same existence." "In technical terms, they are described by the same wave function," it said.
In light of the theory Mass = Energy = Information you have to ask just what they moved. Mass or information?

A "wave function" is information. As this amateur understand it.

Despite the name, no actual teleportation of the photon itself took place. Don't think in terms of Star Trek where an object is dematerialized and reassembled in another location. What actually occurred is that via quantum entanglement, which Albert Einstein called spooky action at a distance, a photon on a satellite in space was made to assume the exact characteristics of a photon on earth which never left the earth. Basically it was information about the photon that was teleported and copied onto the photon on the satellite, rather than the photon itself.
When two particles are entangled, what happens to one particle instantaneously happens to the other particle even though they are physically separated by distance.
Good for the Chinese! But I find it rather sad that MIT, a great scientific institution, is reporting on the achievement of someone else instead of being the one doing the achieving.
