Quantum computer breakthrough as scientists show vital behaviour for first time
Scientists have demonstrated new behaviour, vital for the creation of quantum computers, that marks a major breakthrough.
For the first time, researchers were able to show in an experiment that a variety of quantum computing pieces, taken together, were more accurate than the sum of their parts.
Individually, quantum computers are built out of a range of different pieces, some of which can sometimes break. But in the new experiment, scientists showed that those pieces stuck together can be less prone to error than any particular part.
Such behaviour will be necessary if quantum computers are ever relied on for practical purposes. Scientists suggest that the technology could one day change the world – by allowing us to do calculations more quickly than ever thought possible – but fundamental work like this must first be conducted to ensure those calculations are trustworthy.
The study, ‘Fault-tolerant control of an error-corrected qubit’, is published today in Nature.
