Chinese scientists claim to have built the world’s fastest programmable quantum computers , which appear to crack problems that are currently not feasible for ”classical” non-quantum computers. The researchers led by Pan Jianwei from the University of Science and Technology of China (USTC), said one of the quantum computing systems — Zuchongzhi 2.1 — is a million times more powerful than its nearest competitor, Google ’s Sycamore. Their programmable superconducting quantum computer, named after a 5th-century mathematician, is 10 million times faster than the world’s fastest supercomputer , the scientists said . Besides, their photonic quantum computer based on light…
