The world's first integrated quantum communication network

Chinese scientists have established the world's first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a ...

Simple silicon coating solves long-standing optical challenge

Quick bursts of laser light, lasting less than a trillionth of a second, are used in a range of applications today. These ultrashort laser pulses have allowed scientists to observe chemical reactions in real-time, image delicate ...
