Experiments on Google's 67-qubit Sycamore processor show that operations enter
Chinese scientists have developed a 504-qubit quantum computing chip to make it available to researchers worldwide via a new cloud computing platform.
Chinese researchers use conventional semiconductors to create a quantum light source - an important component for making quantum chips.
If today's most powerful supercomputers need 9,000 years to solve this problem, light quantum chips only need a few millionths of a second.
