    Quantum encryption is now fast enough for voice calls

    Quantum encryption is theoretically a dream for security, as you can't even inspect the data without altering it. However, it's currently several times slower than the conventional kind, which makes it impractical for voice calls or streaming video. Science may have come to the rescue, though: researchers have developed a quantum encryption key distribution system that promises to be five to 10 times faster than existing methods, or roughly on par with conventional encryption when run in parallel. The trick was to cram more data into each photon.

    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.
