Light from behind a black hole

…while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,” bending around the back of the object. Thanks to this strange phenomenon, astronomers have, for the first time, observed the light from behind a black hole.

Einstein has been proven right. Again.

SpooQy-1 action at a distance!

“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” says Aitor Villar, lead author of the study. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”

OK, OK, so it’s not the first time quantum entanglement has been demonstrated. But it sure is the smallest. Only 20 cm by 10 cm!

Now we only need a few thousand of these things and a way of somehow making tangled photons actually carry encrypted messages…

(Sorry, thinking of the SF novel I should have published by now…still figuring out the last two chapters!)
