The new method has the potential to accelerate quantum computations by a factor of a thousand, bringing fault-tolerant quantum computers a significant step closer. Quantum computers remain highly vulnerable to errors and tiny disturbances from their surroundings. The longer a quantum operation takes to complete, the more time there is for those errors to build up. Researchers at Chalmers University of Technology in Sweden have now developed a method that can perform a broad range of advanced quantum operations more than a thousand times faster. The advance tackles a major obstacle in the field and could help move quantum computing closer to becoming fault-tolerant.
