Physical Superintelligence uses AI to crack a two-decade-old quantum computing puzzle

Physical Superintelligence (PSI) has used artificial intelligence to solve a quantum computing problem that had remained open for roughly two decades, a result the firm says can redirect research away from unproductive paths and toward better-optimized efforts. The breakthrough positions AI as a tool for redefining how quantum computing research is prioritized rather than merely accelerating existing work. PSI's finding arrives as AI and quantum computing increasingly converge as adjacent frontiers for venture and institutional capital. What to watch next is whether independent researchers reproduce the result and whether PSI discloses the specific problem solved and the methods used.
