And then there are quantum computers. Pan Jianwei, a leading Chinese quantum scientist, says that the first general-purpose Chinese quantum computer could have a million times the computing power of all other computers presently in the world. In the computers we use today, information is encoded in a series of bits set as either 1 or 0. In a quantum computer, bits would theoretically be able to hold one, both, or some combination of these states. They could be used to speedily crack encrypted messages or solve complicated research problems involving anything from weather modeling to fusion research and biomedicine, because quantum bits allow certain calculations that happen one by one on a standard computer to occur simultaneously.
