SCIENTISTS IN CHINA have created a quantum smartphone that cannot be hacked. The phone comes with a built-in module and a special SIM card that can encrypt and decipher voice calls using “quantum key distribution”, Science Daily reported on Tuesday. A number of countries have been working on similar devices, but China's looks like

      The article says Samsung has already released one in South Korea, so it seems like it’d be pretty easy to confirm.

      Edit: Looks like it does exist, has existed for two years, and so it’s very believable that China has one too. No reason to lie about it really

      I wasn’t really disputing that the phone exists, more that it performs the way that they say it does. I’m not really sure how you would test it. From my very limited understanding, it’s already incredibly difficult to break conventional encryption.

          From my understanding, the main benefit of the quantumness was the inability of third parties to intercept data without changing it. But it sounds like this system relies on a series of base-stations relaying the data over fiber optic cables. Each of these base stations have access to all the keys, per Yogthos’ article.
