• Resumen

  • On 21 June, the Chinese Academy of Sciences hailed a breakthrough--a major upgrade to a kind of quantum device that measures magnetic fields. Then the announcement vanished, after a Hong Kong newspaper pointed out the potential military implications: the invention could help China lock down the South China Sea. Magnetometers have been used to detect submarines since the second world war. They do this by measuring an anomaly in Earth's magnetic field--like one caused by a giant hunk of metal.
