The Internet just got faster.


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.


Quantum teleportation, or entanglement-assisted teleportation, is a process by which a qubit (the basic unit of quantum information) can be transmitted exactly (in principle) from one location to another, without the qubit being transmitted through the intervening space. It is useful for quantum information processing, however it does not immediately transmit classical information, and therefore cannot be used for communication at superluminal (faster than light) speed. It also does not transport the system itself, and does not concern rearranging particles to copy the form of an object.

The seminal paper first expounding the idea was published by Charles Bennett and coauthors in 1993.[1] It was first confirmed experimentally in 1997 by a group in Innsbruck [2] and has subsequently been shown to work over distances of up to 16 kilometers.[3]
