Q-Net Adds a Node, and a Hospital Stops Losing Records

When the regional public hospital in Jakarta cut over to a fresh Q-Net node this month, the change nobody photographed was the one that mattered: patient records now move between clinics over an unbreakable key exchange, and the forged-access incidents that plagued the old network have stopped. Quanta Lattice Systems, which supplied the hardware, notes the link secures the channel without moving data faster than light — the entanglement guarantees privacy, not speed, a distinction its engineers repeat to correct persistent public confusion. "People think we teleport the files. We just make them impossible to steal," said Dr. Wei-Lin Tan of the Singapore Institute, who consulted on the rollout. For records clerk Ibu Sari Wulandari, the payoff is mundane and total: a mother's history follows her to any ward, uncopied and unaltered. The Singapore Institute's larger processor work continues on the same backbone, with a demonstration expected next month.
