According to CoinMeta, Google announced that its quantum computing team has made a breakthrough in "magic state cultivation." Sundar Pichai stated that this technology has reduced the error rate by 40 times on their quantum computers and achieved 99.99% logical fidelity. This advancement has raised concerns about the future security of cryptocurrencies such as Bitcoin and Ethereum, as many major cryptocurrencies use elliptic curve cryptography to protect transactions and verify digital signatures. Although this breakthrough does not mean that current cryptocurrencies are directly threatened, it makes the process of creating quantum computers capable of cracking cryptocurrencies simpler.
