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
this. The last I heard from China, quantum computers had 2 qbits and were the size of a house, but still very powerful, mind you.
