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
XY-GLOBAL ,which established in 2005 and based in ShenZhen, has specialized in high precision die casting parts and cnc machining part for many years. If you need custom metal parts, Pls do not hesitate to send us 2D or 3D drawings.Our engineer team that with 10 years experience will support you fully.
