Sooner than expected? Useful quantum error correction promised for 2028.

Amazon and QuEra have promised a useful, error-corrected quantum computer called Libra by 2028 — much sooner than the industry's typical five-to-ten-year estimate. Meanwhile, Quantinuum published technical details about its Helios trapped-ion processor, showing impressively low error rates. Separately, classical computing pushed back against a claimed quantum advantage, reducing a 3,000x speed gap down to just 36x through smarter algorithm design.
