Quantum entanglement could mean completely secure data transfer
By tapping into Albert Einstein's idea of "spooky action at a distance," researchers at the University of Copenhagen's Niels Bohr Institute have discovered what might be the key to completely secure data transfer -- keeping particles "entangled" for up to an hour. Until now, the link between two entangled systems could only be maintained for a fraction of a second. This development could enable a direct link between two systems of communication -- you do something to one and the other will "know." Although limited to the lab right now, scientists are working on practical applications for networking and the internets. Hey, SSH maybe it's time you started watching your back.

First light wave quantum teleportation achieved, opens door to ultra fast data transmission
Mark this day, folks, because the brainiacs have finally made a breakthrough in quantum teleportation: a team of scientists from Australia and Japan have successfully transferred a complex set of quantum data in light form. You see, previously researchers had struggled with slow performance or loss of information, but with full transmission integrity achieved -- as in blocks of qubits being destroyed in one place but instantaneously resurrected in another, without affecting their superpositions -- we're now one huge step closer to secure, high-speed quantum communication. Needless to say, this will also be a big boost for the development of powerful quantum computing, and combine that with a more bedroom friendly version of the above teleporter, we'll eventually have ourselves the best LAN party ever.
