Construction begins at quantum facility big enough to break Bitcoin
PsiQuantum has begun construction of a new Chicago facility designed to house a 1 million-qubit quantum computer, a scale some researchers believe could eventually threaten Bitcoin’s cryptography. The company says the project is aimed at making quantum computing commercially useful, including for advanced AI and large-scale computing tasks, not for attacking blockchain systems. Still, the development is likely to intensify debate in the crypto world, where developers are already discussing defenses against future quantum threats. Although experts disagree on how soon quantum computers could realistically break Bitcoin, the project marks a major milestone in the race toward practical quantum computing.
