Quantum computers might soon actually be useful, researchers have said after a new breakthrough. A new study showed that a quantum computer could be used for calculations that are beyond the capabilities of our current best classical – or non-quantum – computers. It means that the technology could soon be useful in practical applications, the researchers suggest. For years, quantum computing experts have been hopeful that the technology could allow for entirely new kinds of calculations, which might be useful across battery research, medicines and more. But the current versions are given to a host of problems, including the fact that they are prone to errors. Quantum computers need to be able to fix those errors more quickly than they accumulate. But even the best quantum computers have struggled to do so, meaning that practical use of the technology has remained beyond our grasp. New research from IBM showed that those errors could be mitigated, however, and a quantum computer could be used in ways that a classical computer could not. As such, the results “herald further opportunities for quantum processors to emulate physical systems that are far beyond the reach of conventional computers”, scientists away from the research say. Unlike many other similar breakthroughs – which focus on the extra speed that a quantum computer can provide – this new research focuses on the scale of the computer. Researchers used more 127 qubits, the equivalent of bits on a classical computer, to do research that classical computers do not have enough memory for. The breakthrough is described in a new paper, ‘Evidence for the use of quantum computing before fault tolerance’, published in Nature today.

Threads says it has been forced to limit how many posts people can see, amid an increase in “spam attacks”. The announcement drew mockery from Elon Musk, who had been widely criticised for introducing such “rate limits” on his own site, Twitter. Adam Mosseri, who serves as the head of Instagram and therefore Threads at Meta, said in a post on the site that it was being hit by more spam attacks and that it would have to take a range of responses as a result. “Spam attacks have picked up so we’re going to have to get tighter on things like rate limits, which is going to mean more unintentionally limiting active people (false positives),” he wrote. “If you get caught up [in] those protections let us know.” The change means that users who use Threads the most might run into limits on how many posts they can see and whether they can view the app. He did not give any indication of where the rate limit would be set or how many people mighttbe expected to run into problems. Threads users have complained about a significant increase in the amount of spam on the site, including in the replies to Mr Mosseri’s post. Mr Mosseri has made a number of announcements about the future of Threads on the site. The company – which appears to have been surprised by the success of its own app – has been looking both to add new and widely requested features as well as deal with any technical problems caused by the success of the app. The change drew mockery from Elon Musk, who announced days before the launch of Threads that Twitter would start rate limiting, in what he said was an attempt to stop AI companies scraping Twitter for data to train its models. That led to major problems for Twitter users, who were unable to see posts and more, and those technical issues have been pointed to as one of the reasons that so many users were eager to sign up to Threads in the first place. Mr Musk laughed and posted “copycat” in response to a screenshot of Mr Mosseri’s post. Mr Musk introduced his own rate limits earlier this month. But he announced the numbers of posts that users would be able to see – and did not invite feedback from those who might be swept up in the change.
