China has unveiled its latest photonic quantum computer, Jiuzhang 4.0, with researchers saying it can outperform the world’s fastest classical supercomputer by a vast margin, further strengthening Beijing’s push towards quantum supremacy. The results, published on May 13 in the peer-reviewed journal Nature, mark the latest milestone in China’s rapidly advancing quantum programme led by a team of scientists at the University of Science and Technology of China headed by Chinese quantum physicist Pan Jianwei. Jiuzhang 4.0 completed a Gaussian boson sampling task in just 25 microseconds – a calculation they estimated would take the world’s most powerful supercomputer, El Capitan in the United States, more than 10^42 years to finish, according to the university in the eastern city of Hefei.
