China launched the world's first quantum experiment satellite on Tuesday, taking a big step in building a space-based quantum communication network that would be virtually uncrackable.The satellite has been named "Micius" after a 5th century B.C. Chinese philosopher and scientist who is credited as being the first person in history to conduct optical experiments.

The satellite will create pairs of so-called entangled photons, beaming one half of each pair down to base stations in China and Austria.This special kind of laser has several curious properties, one of which is known as "the observer effect" - its quantum state cannot be observed without changing it.

So, if the satellite were to encode an encryption key in that quantum state, any interception would be obvious. It would also change the key, making it useles
