Crypto News
Google says its Willow chip can use a technique called magic state cultivation to cut quantum errors about 40x, reaching 99.99% accuracy. The result has renewed concern about whether advances in quantum computing could bring Bitcoin’s so-called Q-Day closer.
Why it matters
Bitcoin relies on cryptography to secure transactions and wallets. A sufficiently capable quantum computer could threaten some of the cryptographic methods used by cryptocurrencies, making progress in reducing quantum errors relevant to long-term security planning.
Market impact
The reported benchmark is not evidence that Willow can break Bitcoin’s cryptography. It does, however, keep quantum resistance on the agenda for Bitcoin developers and investors monitoring the network’s long-term security.
Frequently asked questions
