What happened
Google's Quantum AI team has demonstrated a method called magic state cultivation on its Willow processor, reducing errors in preparing quantum magic states by about 40 times. The technique reached 99.99% logical fidelity in testing. Google's chief executive, Sundar Pichai, announced the advance.
Why it matters
Google says the advance takes it another step closer to building a useful, error-corrected quantum computer. Commentators have also raised concerns about what the advance means for the security of cryptocurrencies such as Bitcoin and Ethereum.
