Scientists just made quantum computer operations 1,000 times faster
Researchers at Chalmers University of Technology have developed a method to perform quantum operations 1,000 times faster, addressing a major hurdle in quantum computing. By increasing speed, the method reduces the window for environmental noise to cause errors in delicate quantum states.
Why it matters
Faster, more reliable quantum operations are a prerequisite for achieving fault-tolerant quantum computing, which could revolutionize fields like drug discovery and cryptography.
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.
Quantum computers could eventually transform areas such as drug discovery, energy technology, cryptography, artificial intelligence, and logistics. Before that can happen, however, these machines need to become much more dependable.
A major challenge is that quantum computations can be disrupted by extremely small environmental effects. Electrical noise, cosmic radiation, and overheating can all introduce errors while information is being processed.
