Sooner than expected? Useful quantum error correction promised for 2028.
Define “useful”?
Elsewhere, beyond-classical quantum hardware, plus classical computing fires back.

Quantum computing news usually picks up near the end of the year, as companies try to provide evidence that they are hitting benchmarks on time. However, there have been interesting announcements as the summer starts this year, from incremental progress to attention-grabbing promises. As we did earlier this month, Ars has a rundown of some of the most significant announcements.
These include a promise of useful, error-corrected quantum computing as soon as 2028, details on an updated trapped ion processor, and a case in which claims of quantum supremacy have been cut back a bit thanks to advances in more traditional algorithms.
2028 is remarkably soon
Many people in the field expect that useful quantum computers are still about five to 10 years away....
