Singapore's Privacy War Reopens Before the Processor Even Runs

SINGAPORE — Six days before the Singapore Institute demonstrates its million-qubit processor over the Q-Net backbone, the fight has moved from the laboratory to the street, and it is not about qubits. It is about what an unbreakable line does when the wrong hands hold it. The Q-Net's promise — encryption no eavesdropper can crack — was sold for a decade as a shield for the ordinary citizen. This week, a coalition of civil-liberty groups stood outside the Institute to argue the shield has a second edge: a channel no one can read is also a channel no one can audit, and a state that speaks in perfect secrecy answers to no one. "You cannot subpoena a line you cannot open," one organizer said, and the phrase spread. The Institute insists the mathematics is neutral, indifferent to who wields it. That is precisely the complaint. A tool that protects the dissident's message with the same perfection that seals the ministry's — the demonstration will prove the machine works. It will not settle whom it works for.
