"JiuZhang 3 is million times faster than predecessor and light years ahead of world’s fastest supercomputer... solved ultra-complicated mathematical problem within millionth of second, more than 20 billion years quicker than world’s fastest supercomputer... 1 million-fold increased calculation speed,.. uses 255 photons for calculations, each carrying a qubit... eventually requiring tens of thousands – or even millions of qubits – along with robust error correction capabilities to actualise large-scale and high-speed quantum computer"
