    And it looks like it'll be as easy as clicking on an app and taking a pic with the camera on your phone.

    Gibberish to me
    The quantum process that these guys exploit is the way light sources emit photons.

    The set up is simple in principle. Each pixel senses the number of photons that arrive in a certain period of time. These photons are converted into electrons, which are then amplified by a factor determined by the camera’s sensitivity setting (ISO setting).

    The security implications of this are important. In cryptography, there is a well known idea called Kerckhoffs’s principle that states that the security of a cypher should lie entirely in the key. So while every other aspect of a security system can be public, the information it carries will remain secure as long as the key is also secure.


    And applications? Secure credit card transactions are only the beginning. A quantum random number generator that works at 1 Mbps can also secure emails and even phone calls.


    There ought to be significant demand for this kind of service given the wholesale eavesdropping that various states have indulged in recently. So it’s not beyond the realms of possibility that some governments will want to regulate the use of this kind of technology.
    It's already passed standard tests random generators have to pass and it would take....
    “If everybody on earth used such a device constantly at 1Gbps, it would take 10^80 times the age of the universe for one to notice a deviation from a perfectly random bit string,”
