Scientists just made quantum computer operations 1,000 times faster

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.

Why Quantum Computers Are So Error-Prone

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.

Traditional computers can experience errors too, but decades of development have produced reliable error correction methods that can quickly detect and repair them. Quantum systems are much harder to protect because the information they use is extraordinarily delicate.
