Unxibelelwano oluntsonkothileyo lwe-Quantum
Unxibelelwano oluyimfihlo lwe-Quantum, olukwabizwa ngokuba yi-quantum key distribution, yeyona ndlela yonxibelelwano ethe yangqinwa ikhuseleke ngokupheleleyo kwinqanaba langoku lokuqonda komntu. Umsebenzi wayo kukusasaza ngokuguquguqukayo isitshixo phakathi kuka-Alice noBob ngexesha lokwenyani ukuqinisekisa ukhuseleko olupheleleyo lonxibelelwano.
Unxibelelwano olukhuselekileyo lwemveli kukukhetha kwangaphambili kwaye unike isitshixo xa u-Alice noBob bedibana, okanye uthumele umntu okhethekileyo ukuba ahambise isitshixo. Le ndlela ayilunganga kwaye iyabiza, kwaye idla ngokusetyenziswa kwiimeko ezikhethekileyo ezifana nonxibelelwano phakathi kwenkwili kunye nesiseko. Ukuhanjiswa okungundoqo kwe-Quantum kunokuseka umjelo we-quantum phakathi kuka-Alice no-Bob, kwaye unikeze izitshixo ngexesha langempela ngokweemfuno. Ukuba uhlaselo okanye ukuphulaphula kwenzeka ngexesha lokusasazwa okungundoqo, bobabini u-Alice noBob banokuzibona.
Ukusabalalisa okungundoqo kwe-Quantum kunye nokufunyanwa kwe-photon enye zezona teknoloji eziphambili zonxibelelwano olukhuselekileyo lwe-quantum. Kwiminyaka yakutshanje, iiyunivesithi eziphambili kunye namaziko ophando enze inani elikhulu lezifundo zovavanyo kwiitekhnoloji eziphambili zonxibelelwano lwe-quantum.Iimodyuli ze-Electro-optickwayeiilaser zobubanzi obumxinwaiphuhliswe ngokuzimeleyo yinkampani yethu isetyenziswe ngokubanzi kwiinkqubo zokusasaza eziphambili ze-quantum. Thatha unikezelo oluqhubekayo lwesitshixo se-quantum njengomzekelo, njengoko kubonisiwe kulo mfanekiso ulandelayo.
Ngokwale migaqo ingasentla, i-electro-optical modulator (AM, PM) yinxalenye ebalulekileyo yenkqubo yokuvavanya ukusabalalisa okungundoqo kwe-quantum, enekhono lokulungelelanisa i-amplitude okanye isigaba sentsimi ye-optical field, ukwenzela ukuba uphawu lokufaka lukwazi isasazwa nge-optical quantum. Inkqubo idinga imodyuli yokukhanya kokukhanya ukuba ibe nomlinganiselo ophezulu wokutshabalala kunye nelahleko ephantsi yokufaka ukwenzela ukuvelisa umlinganiselo ophezulu wokuphela kwe-pulsed light signal.
