China says it has launched the world’s first quantum satellite, a project Beijing hopes will enable it to build a coveted “hack-proof” communications system with potentially significant military and commercial applications. “The satellite’s two-year mission will be to develop ‘hack-proof’ quantum communications, allowing users to send messages securely and at speeds faster than light,” Xinhua reported. The Quantum Experiments at Space Scale, or Quess, satellite programme is part of an ambitious space programme that has accelerated since Xi Jinping became Communist party chief in late 2012. “There’s been a race to produce a quantum satellite, and it is very likely that China is going to win that race,” Nicolas Gisin, a professor and quantum physicist at the University of Geneva, told the Wall Street Journal. Highly complex attempts to build such a “hack-proof” communications network are based on the scientific principle of entanglement.
