Itumanaho rya Quem

Itumanaho rya Quem

Itumanaho ryibanga, rizwi kandi nka Quanim Ikwirakwizwa ryingenzi, nuburyo bwonyine bwitumanaho bwagaragaye ko umutekano wumuntu wubumenyi. Nibikorwa ni ugukwirakwiza urufunguzo hagati ya Alice na Bob mugihe nyacyo kugirango umutekano witumanaho wuzuye.

Itumanaho gakondo ryizewe ni ukubanziriza kandi tugashyikiriza urufunguzo mugihe Alice na Bob bahuye, cyangwa wohereze umuntu wihariye gutanga urufunguzo. Ubu buryo ntibwuzuye kandi buhenze, kandi ubusanzwe ikoreshwa mubihe byihariye nko gushyikirana hagati yitabwa hamwe nishingiro. Isaranganya ryingenzi rishobora gushyiraho umuyoboro wa Quantu hagati ya Alice na Bob, hanyuma utange urufunguzo mugihe nyacyo ukurikije ibikenewe. Niba ibitero cyangwa gutega amatwi bibaho mugihe cyingenzi, Alice na Bob birashobora kubimenya.

Ikwirakwizwa ryingenzi hamwe no kumenya photon imwe ni tekinoroji yingenzi ya Ferim itumanaho ryizewe. Mu myaka yashize, kaminuza zikomeye n'ibigo by'ubushakashatsi byakoze umubare munini w'ubushakashatsi bugeragejwe ku ikoranabuhanga ry'ingenzi ry'itumanaho rya Quafyumu.Amashanyarazi ya electro-optickandiUmuyoboro mutoKwigenga byateye imbere na sosiyete yacu yakoreshejwe cyane muri sisitemu yingenzi yo kugabura. Gufata igihangange gikomeza kugabura nkurugero nkurugero, nkuko bigaragara mu ishusho ikurikira.

Dukurikije amahame yavuzwe haruguru, modulator ya electro-optique (am, PM) nigice cyingenzi cyikizamini cya Quflim, kiba gifite ubushobozi bwo gukwirakwiza amplitution cyangwa icyiciro cyo gutangaza gishobora koherezwa binyuze muri optique optique. Sisitemu isaba modutor yumucyo kugirango igabanye ikigereranyo kinini hamwe nigihombo gito cyo kwinjiza kugirango utange ikigereranyo cyo hejuru yikimenyetso cyo hejuru.
