Quantum ihishe itumanaho

Itumanaho ryibanga rya Quantum, rizwi kandi kwizina rya kwant, ni bwo buryo bwonyine bwo gutumanaho bwagaragaye ko butekanye rwose kurwego rwubu rwubwenge. Nibikorwa ni ugukwirakwiza byimazeyo urufunguzo hagati ya Alice na Bob mugihe nyacyo kugirango umutekano wuzuye witumanaho.

Itumanaho gakondo rifite umutekano ni uguhitamo mbere no gutanga urufunguzo mugihe Alice na Bob bahuye, cyangwa kohereza umuntu udasanzwe gutanga urufunguzo. Ubu buryo ntibworoshye kandi buhenze, kandi mubusanzwe bukoreshwa mubintu bidasanzwe nko gutumanaho hagati yubwato na base. Ikwirakwizwa rya Quantum rishobora gushiraho umuyoboro wa kwant hagati ya Alice na Bob, kandi ugatanga urufunguzo mugihe gikwiye ukurikije ibikenewe. Niba ibitero cyangwa gutega amatwi bibaye mugihe cyo gukwirakwiza urufunguzo, Alice na Bob bombi barashobora kubimenya.

Ikwirakwizwa rya Quantum hamwe na fotone imwe ni tekinoroji yingenzi yo gutumanaho kwizewe. Mu myaka yashize, kaminuza nkuru n’ibigo by’ubushakashatsi byakoze ubushakashatsi bwinshi bw’ubushakashatsi ku ikoranabuhanga ry’itumanaho rya kwant.Abayobora amashanyarazinaInzira ntoyayigenga yatejwe imbere nisosiyete yacu yakoreshejwe cyane muri sisitemu yo gukwirakwiza kwant. Fata impinduka zihoraho za kwant urufunguzo nkurugero, nkuko bigaragara mumashusho akurikira.

Ukurikije amahame yavuzwe haruguru, moderi ya electro-optique (AM, PM) nigice cyingenzi cya kwant urufunguzo rwo gukwirakwiza sisitemu, ifite ubushobozi bwo guhindura amplitude cyangwa icyiciro cyumurima wa optique, kugirango ibimenyetso byinjira bibe kwanduzwa binyuze muri optique. Sisitemu isaba urumuri rukomeye rwumucyo kugira igipimo kinini cyo kuzimangana no gutakaza igihombo gito kugirango habeho igipimo kinini cyo kuzimangana cyerekana urumuri.
