China breakthrough could make ‘fault-tolerant’ quantum computing a reality

Chinese researchers advance quantum simulation technology with clear and flexible system that ‘deserves to be included in textbooks’. The development will make it easier to manipulate and observe simulated quantum systems and solve intractable physics problems, they said. — SCMP

Leading quantum physicist Pan Jianwei and his team at the University of Science and Technology of China have developed an artificial quantum system that has groundbreaking implications for physics and could pave the way for fault-tolerant quantum computing.

The researchers used photons to simulate an interaction between charged particles known as the fractional anomalous quantum Hall effect, previously observed only in electrons, according to a paper published this month by the journal Science.
