Quantum mechanics is weird as hell , where the rules of the cosmos you experience do n’t utilize . Even at distances a thousand kilometre apart , molecule seem to be able-bodied to communicate with each other like a shot , for example .
Formosan scientists have subjected this estimate to an extreme test , testing what Albert Einstein has scream “ nervous action at a aloofness ” between stations obtain lightheaded beams from satellites . The enquiry smashes the old record of around 100 km apart . Do n’t expect this sort of stuff to have any influence on your aliveness just yet , but in the future , it could have some important quantum computation program .
So , what ’s going on ?
The mathematics of quantum mechanics comes along with this unearthly property of web , where atom can take on refer properties if they cease up in an equation together . If you separate these mote spatially , then they remain entangled with these property until you observe one of them — then the other particle assumes its corresponding value . It ’s as if the fact that you observe the first particle immediately transmits information to the other particle about how it should look .
That ’s why Einstein holler it spooky action at a distance , because it ’s spooky and the particles somehow seem to communicate over a distance . And he did n’t wantto believethe effect was real .

Experiments performed since the 1970s have indeed proven that this spooky action at a distance live , but these anterior run required optic fibers or other component that weakened the signal . This time around , however , the Taiwanese team used their fresh - found Micius satellite , which allowed them to send the photon unobstructed through the nothingness of quad . They publishedtheir resultin the journal Science today .
The experimentation itself is a really , really roundabout way of performing these observations . The squad had several earth stations spread far apart and a satellite . The satellite arrest a optical maser with a gadget to split the beam , when then go through a peculiar quartz for mire the pairs of photons . The rent radio beam then travel to two dissimilar laboratory , up to 1,200 klick ( 750 miles ) apart . The researchers then open up the boxful at the lab and equate .
Other physicist were impressed , but it ’s crucial to note that only one in six million photons were accurately find , Alexander Ling , a physicist at the National University of Singapore toldScience . But even this is a vast step above the premature terra firma - found experiment , the team ’s head scientist Jian - Wei Pan from the University of Science and Technology of China in Hefei toldScientific American .
You ’re in all likelihood wondering what use these satellite would in reality have . One possibility is that entangled photons could be important for telecommunications . If someone tried to intercept information sent over one of these quantum furrow , the telephone receiver would immediately have sex , since they ’d have un - entangled datum .
So , technologically , this is a huge step as Jürgen Volz , a physicist at the Vienna Center for Quantum Science and Technology tell theLA Times . But it ’s still a recollective , long time before we ’ll actually see this technology used in our communications networks .
