China is due to launch the world ’s first quantum communication satellite into space this July , as reported byDigital Trends . The 500 - kilo ( 1,100 pounds ) box of complex bolt is part of the novelQuantum Experiments at Space Scale(QUESS ) mission , which will ride through the air on the Long March 2D rocket engine from the Jiuquan Satellite Launch Center in the Gobi Desert .
This satellite aims to test the decidedly skittish phenomenon ofquantum web . As it change by reversal out , two molecule roleplay as a co - dependent pair when they are separated by huge distance . Their attribute are linked , or “ mirrored , ” and the two enactment as one individual organization .
enigmatically , a measurement on one particle will be a measurement describing the intact entangled organisation ; it is as if one particle in the pair “ hump ” what measurement has been direct on the other , despite the fact that there is no method in which any physical information is being actively transmitted between the two particles .

This means that a satellite could , say , contain one particle whereas one on the open of the Earth could contain another , and both could be in one embroiled system . instead , two particles on the ground , separate by a vast distance , could be tangle by the planet itself . This is just what the two - year - long QUESS mission aims to try out when it enters into a Sun - synchronous range at an altitude of 600 kilometers ( 375 knot ) over the coming month .
Ground station across China , quick to hire in a bit of quantum web with QUESS , have been under construction for some time now . In plus , theAcademy of Sciencesin Vienna , Austria , will also be help out in this open up experimentation .

If quantum entanglement across hundreds of kilometers is indeed possible , theninformation encryptedin quantum system could theoretically be glow across the world – and this type of cryptography is seen by many cryptologist as beingtheoretically impossible to break . Viewing part of an embroiled system would cause it to collapse and make the selective information incorporate within it unreadable .
“ There are many bottlenecks in the information security , ” said Pan Jianwei , the project run , at a recent seminar in Shanghai , as report bygbtimes . “ The Edward Snowden case has state us that the information in the transmittance networks are give away to risks of being monitored and being assail by hackers . ” He went on to tell thePeople ’s Dailythat QUESS will be part of a long - term goal to ensure that “ online transfers and payments can be vouch through quantum communication for every consumer . ”
