Microsoft announced the Majorana 2 topological quantum chip at the annual Build conference, claiming its reliability is 1,000 times higher than the previous generation, with an average qubit lifespan of 20 seconds, and some lasting about 1 minute. Microsoft stated that AI Agent tools help the team accelerate material screening, automate measurement, and optimize manufacturing processes, and they expect to move closer to scalable quantum computing by 2029. Decrypt pointed out that this progress has reignited discussions about the future threat of quantum computing to Bitcoin's digital signature security, but it does not mean that current quantum computers can attack Bitcoin.
