"measurement technologies process tiny fraction quantum generated bandwidth at a time, overcome using parametric homodyne detection achieving parallel quantum processing achieving orders of magnitude higher speed/ capacity... ran 23 independent spectral channels for quantum key distribution... demonstrated multiplexed quantum teleportation... eventually support 1,000s channels... drastically faster and more reliable quantum key distribution for encryption... scalable, high-speed quantum networks"
