Google announced a major breakthrough in quantum computing with its magic state cultivation method on the Willow quantum computer, published in Science. The team reduced errors by a factor of 40 and achieved a record logical fidelity of 99.99% for T-states. This discovery represents a significant step toward creating quantum computers capable of solving problems impossible for current machines. It raises concerns for cryptocurrencies like Bitcoin and Ethereum, which rely on elliptic curve cryptography to secure their transactions. Experts clarify, however, that the technology is not yet at a stage capable of directly threatening current digital assets.
