'US scientists move toward speed-of-light internet...'

'American scientists say they have taken a big step forward towards the development of quantum computing, a process they believe could form the basis of a new form of internet that would work at the speed of light.

In the American Journal of Science, researchers say they have instantaneously teleported information between two unconnected atoms one metre apart.

Quantum computing is an effort to harness the bizarre laws that operate in the sub-atomic world into practical devices that would revolutionise the speed at which we can share and process information.

One of the key principles that empowers the concept is that in quantum mechanics, atomic particles can exist in two states at the same time.

This makes them far more useful for carrying out complex calculations than conventional computer bits that are either one or zero, on or off.

Another weird aspect of the quantum state is that atoms can be inextricably linked to other atoms, no matter how far apart they are.

Change the characteristics of one and, like magic, the other changes too.'

so does quantum entanglement work instantaneously or at the speed of light? which is it, they say both...

Very good question, anon.

I'm surprised more hasn't been made (in the synchrosphere and elsewhere) about this development- which struck me as astonishing.

There's an update to follow on this story.
