    The article further describes China's breakthrough in quantum communications. The author states China is ahead of the US. This may be true but given this stuff is in the spook realm, why would they want to announce their progress? However, the Chinese investment in basic science is huge and starting to pay off.

    Another article on China's efforts in quantum computing and encryption along with some comments on their approach to research and space intentions. Money can get things done.

    A normal compass doesn't require satellites etc., to work, however it is magnetic and as such it is subject to variations in the magnetic field. These changes are can be mitigated by the use of gyroscopic compasses in ships etc., but if a gyroscope is toppled it has to reset. What is needed is a quantum version of GPS where you are able to fix you position accurately in 3D space without having to visually reference known marks such as stars, headlands, etc. Maybe a quantum version of the INS (Inertial navigation System) for a start.
