    Default Quantum cryptography at the speed of light

    Imagine having your MRI results sent directly to your phone, with no concern over the security of your private health data. Or knowing your financial information was safe on a server halfway around the world. Or sending highly sensitive business correspondence, without worrying that it would fall into the wrong hands.

    Thanks to new research from a team of University of Toronto engineers, these types of perfectly secure information exchanges are one step closer to reality. Published this week in Nature Communications, researchers have designed the first all-photonic quantum repeaters—protocols that ensure data can be carried reliably and securely across longer distances when using quantum cryptography.

    Nice read. Thanks for posting!!

    This was the coolest part!

    "
    “The original question was whether we could transmit polarization over long distances, but that’s boring—then researchers asked, can we do something fancier?” says Professor Lo. “And it turns out we can do quantum teleportation.”
    You won’t be beaming from home to work any time soon, but researchers have already completed experimental demonstrations of beaming states of photons and even atoms from one location to another."

    Well. You might like this then: Quantum teleportation achieved on a microchip the size of a penny - Electronic Products I ran into the article today at work. Check out the pics in the article of what it looked like just a couple of years ago!

    From a room size contraption to the size of a penny. In only 2 years. Insane amount of progress. Full scale Quantum computing is well on its way to being a reality. It will unlock vast amounts of information. Theories can be put to the test in fairly short order. Can lead to peace or our demise. Guess we wait and see which one.

    Once what was yesterday future is today present. Technology is advancing strides, who knows maybe we'll soon with the help of quantum computing be able to solve the issue of teleportation (at least objects, if not living beings.
