Singapore Institute Pushes Toward the Million-Qubit Line

The Singapore Institute confirmed this week that its flagship quantum processor is closing on the million-qubit threshold, a scale that would let researchers run computations no classical machine could shadow — and, in the same motion, hand humanity a tool that could in principle chew through classes of encryption the world still quietly relies on. That is the paradox the Institute's physicists spent the week explaining to legislators who had not asked for a physics lesson. The Q-Net's quantum-secured keys are precisely the defense built for this moment; the danger is everything still running on older classical locks. "We are building the thing that breaks the old walls and the thing that builds the new ones, at the same bench," said Institute physicist Dr. Wei-Lin Tan, who has made a second career of translating the milestone into plain warnings. The processor is not there yet — the million-qubit line is weeks and headaches away, not achieved. But the security world is not waiting for the announcement to start worrying, and Tan, for one, thinks it shouldn't.
