Unxibelelwano olufihliweyo lwe-Quantum
Unxibelelwano oluyimfihlo lwe-quantum, olukwaziwa ngokuba yi-quantum key distribution, yindlela yonxibelelwano kuphela eqinisekisiweyo ukuba ikhuselekile ngokupheleleyo kwinqanaba langoku lokuqonda komntu. Umsebenzi wayo kukusasaza ngokuguquguqukayo isitshixo phakathi kuka-Alice noBob ngexesha langempela ukuqinisekisa ukhuseleko olupheleleyo lonxibelelwano.
Unxibelelwano olukhuselekileyo lwendabuko kukukhetha kwangaphambili nokunika isitshixo xa uAlice noBob bedibana, okanye ukuthumela umntu okhethekileyo ukuba asizise. Le ndlela ayilunganga kwaye ibiza kakhulu, kwaye idla ngokusetyenziswa kwiimeko ezikhethekileyo ezifana nonxibelelwano phakathi kwenqanawa engaphantsi komhlaba kunye nesiseko. Ukusasazwa kwezitshixo zeQuantum kunokuseka umjelo wequantum phakathi kukaAlice noBob, kwaye kunikwe izitshixo ngexesha langempela ngokweemfuno. Ukuba uhlaselo okanye ukuphulaphulwa kwezitshixo kwenzeka ngexesha lokusasazwa kwezitshixo, bobabini uAlice noBob banokuzibona.
Ukusasazwa kwesitshixo se-quantum kunye nokufunyanwa kwe-photon enye zezona teknoloji ziphambili zonxibelelwano olukhuselekileyo lwe-quantum. Kwiminyaka yakutshanje, iiyunivesithi ezinkulu kunye namaziko ophando enze inani elikhulu lezifundo zovavanyo kwiiteknoloji eziphambili zonxibelelwano lwe-quantum.Iimodulators ze-electro-optickwayeiileyiza ezinobubanzi obumxinwaEziphuhliswe ngokuzimeleyo yinkampani yethu zisetyenziswa kakhulu kwiinkqubo zokusasazwa kwezitshixo ze-quantum. Thatha usasazo lwezitshixo ze-quantum oluguquguqukayo oluqhubekayo njengomzekelo, njengoko kubonisiwe kumfanekiso olandelayo.
Ngokwemigaqo engentla, i-electro-optical modulator (AM, PM) yinxalenye ebalulekileyo yenkqubo yovavanyo lokusasazwa kwesitshixo se-quantum, enokukwazi ukuguqula i-amplitude okanye isigaba sentsimi ye-optical, ukuze isignali yokufaka idluliselwe nge-optical quantum. Le nkqubo ifuna ukuba i-light intensity modulator ibe ne-high extinction ratio kunye ne-insertion loss ephantsi ukuze kuveliswe isignali yokukhanya e-pulsed ratio ephezulu extinction ratio.
