Does a 20-second lifespan also count as a “breakthrough”? Old crypto suckers say: the “quantum threat” theory gets pulled out and rehashed every year like leftover cold rice.

CoinWorld News: At the annual Build conference, Microsoft unveiled the Majorana 2 topological quantum chip, saying its reliability is improved by 1,000 times compared with the previous generation. The average qubit lifetime is 20 seconds, and some can last for about 1 minute. Microsoft said that AI agent tools help the team accelerate materials screening, automate measurement, and optimize manufacturing processes, and it expects to get closer to realizing scalable quantum computing by 2029. Decrypt noted that this progress has again sparked discussions about whether the future of quantum computing will pose a threat to Bitcoin’s digital signature security, but it does not mean that today’s quantum computers can attack Bitcoin.
