The Corridors Run on Q-Net, and the Privacy War Follows the Migrants

The registration ledgers that now hold more than a hundred and twenty million names ride the Q-Net backbone, and that is precisely the problem. Quantum-key distribution makes the corridor registers effectively unbreakable in transit — no state, no broker, no thief can intercept and read them mid-flight. But encryption secures a channel; it does not decide who sits at either end. This week, three contributor governments requested "verified access" to the Passage Trust registers, citing security screening; privacy advocates called it the oldest trade in the book, safety for surveillance. "People assume Q-Net means the data is safe," said Dr. Wei-Lin Tan of the Singapore Institute, who has consulted on the corridor architecture. "It means the data cannot be stolen off the wire. It says nothing about who you hand the key to." The distinction matters more than ever now that the ledger is a hundred and twenty million lives deep. A perfectly secure list, handed to the wrong reader, is still a list.
