- Google says its "magic state cultivation" technique works in practice on the Willow quantum processor, marking what it calls a breakthrough.
- The technique reportedly reduces errors by about 40x, per a Google Quantum AI research scientist.
Why it matters: Google frames a specific, quantified 40x error reduction on its Willow quantum hardware as a breakthrough rather than a roadmap item. For the quantum computing field, the leap is that the technique now works "in practice" on real hardware — and the claim comes with a named practitioner's on-record attestation.
