Kulumikizana kobisika kwa Quantum

Kulumikizana kobisika kwa Quantum

Kuyankhulana kwachinsinsi kwa Quantum, komwe kumadziwikanso kuti quantum key distribution, ndiyo njira yokhayo yolankhulirana yomwe yatsimikiziridwa kukhala yotetezeka kwambiri pamlingo wamakono wa chidziwitso chaumunthu. Ntchito yake ndikugawa makiyi pakati pa Alice ndi Bob munthawi yeniyeni kuti muwonetsetse kuti kulumikizana kuli kotetezeka.

Kulankhulana kotetezeka kwachikhalidwe ndikusankhatu ndikugawa kiyi pomwe Alice ndi Bob akumana, kapena kutumiza munthu wapadera kuti apereke kiyiyo. Njirayi ndi yovuta komanso yokwera mtengo, ndipo nthawi zambiri imagwiritsidwa ntchito pazochitika zapadera monga kulankhulana pakati pa sitima zapamadzi ndi pansi. Kugawa makiyi a Quantum kumatha kukhazikitsa njira yochulukirapo pakati pa Alice ndi Bob, ndikugawa makiyi munthawi yeniyeni malinga ndi zosowa. Ngati kuwukiridwa kapena kutchera khutu kumachitika panthawi yogawa makiyi, Alice ndi Bob amatha kuzizindikira.

Kugawa makiyi a Quantum ndi kuzindikira kwa photon imodzi ndi matekinoloje ofunikira a kulumikizana kotetezeka kwa quantum. M'zaka zaposachedwa, mayunivesite akuluakulu ndi mabungwe ofufuza achita kafukufuku wochuluka pa matekinoloje ofunikira a quantum communication.Electro-optic modulatorsndiyopapatiza linewidth lasersopangidwa paokha ndi kampani yathu akhala akugwiritsidwa ntchito kwambiri pamakina ogawa makiyi a quantum. Tengani kugawa kosalekeza kwa makiyi a quantum monga chitsanzo, monga zikuwonekera pachithunzi chotsatirachi.

Malinga ndi mfundo zomwe zili pamwambazi, electro-optical modulator (AM, PM) ndi gawo lofunika kwambiri la quantum key distribution test system, yomwe ili ndi mphamvu yosinthira matalikidwe kapena gawo la gawo la kuwala, kotero kuti chizindikiro chothandizira chikhoza kukhala. imafalitsidwa kudzera mu optical quantum. Dongosololi limafunikira moduli yamphamvu yowunikira kuti ikhale ndi chiwopsezo chambiri komanso kutayika kocheperako kuti ipangitse chiŵerengero chapamwamba cha kutha kwa pulsed kuwala.
