Using a laser, Chinese engineers at the University of Science and Technology in Shanghai have transported photons across a lake in China.  Whilst this isn't really the same thing as we saw in 'Star Trek,' it does pave the way for instant data transfers that cannot be hacked or intercepted.

In this process, photon transmits its quantum state to another photon, which becomes a clone of the original.

A photon is a discrete particle having zero mass, no electric charge, and an indefinitely long lifetime.  And quantum state is the condition in which a physical system exists.   

Interesting, kind of spooky. I do like the idea that it can not be hacked or intercepted though. :))

I found it interesting that because of the “ultra-bright multi-photon entanglement” thing--whatever that is--the noise in photon detection with this method mainly depends on the position of the moon.

Anyway, assuming that the standard method of non-spoken communication is eventually by quantum teleportation (isn’t that what everyone assumes?), then it spells the end of government eavesdropping. But eavesdropping by governments is big business these days. So will governments try to restrict access to quantum teleported communication methods? If so, how?
