Error-Correction Milestone Lets a Q-Net Link Run a Full Day Unbroken

SINGAPORE — The headline number this autumn is not qubits but hours: a logical qubit held stable across a Q-Net-secured link for a continuous twenty-four-hour run, the Singapore Institute reported this week, its longest coherent operation on the deployed backbone. Two months after the Institute demonstrated a million-qubit processor over the same network, the work has turned from raw scale to endurance — the unglamorous problem of correcting errors faster than physics introduces them. "People ask when the quantum computer will think," said Institute physicist Dr. Wei-Lin Tan, who cautioned yet again that it does no such thing. "It calculates. Our job this year was to make it calculate for a whole day without lying to us." Tan stressed that Q-Net still only secures a channel; it moves no information faster than light and holds no mind. The result matters most to the banks and grid operators who lean on the network's unbreakable keys — for them, a day of stable operation is the whole point.
