China building world's largest quantum facility

China is building the world's largest quantum research facility to develop a quantum computer and other "revolutionary" forms of technology that can be used by the military for code-breaking or on stealth submarines, according to scientists and authorities involved in the project. The National Laboratory for Quantum Information Science will be located on a 37-hectare site next to a small lake in Hefei, Anhui province. Sometime this month developers will be invited to bid for a contract to construct the site, the South China Morning Post reports. Pan Jianwei, China's lead quantum scientist who was playing a key role in the project, told local officials at a briefing in May that technology developed in the facility would be of immediate use to the armed forces, according to Anhui Business Daily newspaper. Quantum metrology, which measures small variations in physical parameters such as gravity with unprecedented accuracy, could significantly improve submarines' stealth operations.
