Teleportation of light particles kudutsa m'mizinda imatitengera sitepe imodzi pafupi ndi intaneti ya quantum

Kuyesa kwaposachedwa komwe kunachitika ku HeiFei, China, ndi Calgary, Canada kwadzetsa chipwirikiti padziko lonse lapansi zasayansi atatsimikizira kuti mafotoni amatha kutumizidwa kudera la quantum kwa mtunda wochulukirapo kuposa kale lonse. 

'teleportation' iyi yatheka chifukwa cha Quantum Entanglement, chiphunzitso chomwe chimatsimikizira mawiri awiri kapena magulu a ma photon sangafotokozedwe ngati akuyenda kapena kuchitapo kanthu ngakhale ali mabungwe osiyana. Kusuntha kwa wina (kuzungulira, kuthamanga, polarization kapena malo) kumakhudza winayo mosasamala kanthu kuti ali kutali bwanji ndi mzake. M'mawu a tinthu tating'onoting'ono, zimakhala ngati mutha kupota maginito amodzi mozungulira pogwiritsa ntchito maginito ena. Maginito awiriwa ndi odziyimira pawokha koma amatha kusuntha wina ndi mnzake popanda kuyanjana.  

(Ndikufewetsa chiphunzitso chomwe chakhala ndi ma voliyumu ndi ma voliyumu olembedwa m'dzina lake ku ndime imodzi, kufanana kwa maginito sikufanana kwenikweni koma kokwanira pazolinga zathu.) 

Momwemonso, kulowetsedwa kwa quantum kumalola kuti tinthu tating'ono tating'ono tigwirizane, mtunda wawukulu woyesedwa, pankhaniyi, kukhala 6.2 kilomita.  

"Chiwonetsero chathu chimakhazikitsa chofunikira pakulankhulana kwachulukidwe," lipotilo likuti, "...  

Chifukwa chomwe izi zitha kupangitsa intaneti kukhala yofulumira ndi chifukwa zitha kuthetsa kufunikira kwa ma cabling onse. Mutha kukhala ndi zithunzi ziwiri zolumikizidwa, imodzi mu seva ndi ina pakompyuta. Mwanjira iyi, m'malo motumiza chidziwitso pa chingwe, chimatumizidwa mosasunthika ndi kompyuta yomwe imayendetsa fotoni yake ndikupangitsa kuti ma photon azisuntha chimodzimodzi. 

Kuyesaku kudakhudza kutumiza ma photon (tinthu topepuka) motsatira mizere ya netiweki ya Fiber Optic kuchokera mbali imodzi kupita ina m'mizinda yomweyi. Ngakhale kuti chiphunzitso cha quantum teleportation chinatsimikiziridwa pafupifupi zaka makumi awiri zapitazo, iyi ndi nthawi yoyamba kuti itsimikizidwe pa intaneti yapadziko lapansi yomwe kulibe cholinga chokha cha kuyesa.  

Zotsatira zakuyesaku ndizambiri, chifukwa zikutsimikizira kuti intaneti ya Quantum singafunike kuti zida zomwe zilipo zisinthidwe kuti zigwiritse ntchito intaneti yothamanga kwambiri. 

Atayandikira Quantumrun, a Marcelli Grimau Puigibert (mmodzi mwa omwe adachita nawo kafukufuku wa Calgary) adatiuza kuti, "Izi zikutifikitsa pafupi ndi Quantum Internet yamtsogolo yomwe ingagwirizane ndi makompyuta amphamvu kwambiri omwe ali ndi chitetezo chotsimikiziridwa ndi malamulo ngati quantum mechanics."
