The development of quantum computers remains in its infancy, but the technology is seen as crucial to future national security. The advanced machines are very different to a modern supercomputer, relying on properties of quantum physics and particles to conduct advanced calculations. In theory, this should allow them to far outstrip the capabilities of traditional computers, which rely on binary ones and zeros to operate.Multiple start-ups have been trying to develop systems that could apply uncrackable new encryption techniques to the internet to defend against a quantum hack. Is the Chinese supercomputer a threat to world security ?
