Google's Willow quantum chip
Many researchers believe that the only way to build a demonstrably useful quantum computer is to allow the computer to correct its own errors. A breakthrough in December from Google Quantum AI researchers offers one path to making this a reality. However, their approach may already be at risk of becoming obsolete.
A major factor preventing quantum computers from fulfilling their promise – solving seemingly intractable problems in materials science, chemistry, logistics, and many other fields – is that they always make errors.
