So far, quantum computers have been held back by their extreme sensitivity to errors and external disturbances. The longer a quantum operation takes, the greater the risk that computational errors will occur. Now, researchers at Chalmers University of Technology, in Sweden, have developed a new method that allows a wide range of advanced quantum operations to be carried out more than a thousand times faster. The breakthrough addresses a well-known bottleneck in the field and paves the way for fault-tolerant quantum computing.
