China already has the world's fastest supercomputer and has now built a crude quantum computer that could outpace today's PCs and servers.
Quantum computers have already been built by companies like IBM and D-Wave, but Chinese researchers have taken a different approach. They are introducing quantum computing using multiple photons, which could provide a superior way to calculate compared to today's computers.
The Chinese quantum computing architecture allows for five-photon sampling and entanglement. It's an improvement over previous experiments involving single-photon sourcing, up to 24,000 times faster, the researchers claimed.
