Quantum encrypted kev sib txuas lus

Quantum Kev sib txuas lus zais, tseem hu ua Quantum Ntsiab Lus Qhia, yog txoj kev sib txuas lus tseem ceeb uas tau ua pov thawj kom tau muaj kev nyab xeeb kiag li ntawm txoj kev siab ntev tam sim no. Nws muaj nuj nqi yog faib rau qhov tseem ceeb ntawm Alice thiab Bob hauv lub sijhawm tiag tiag kom ntseeg tau tias kev sib txuas lus.

Cov kev sib txuas lus nyab xeeb yog ua ntej xaiv thiab muab tus yuam sij thaum Alice thiab Bob ntsib, lossis xa tus neeg tshwj xeeb kom xa tus yuam sij. Hom qauv no yog tsis yooj yim thiab kim, thiab feem ntau yog siv hauv cov xwm txheej tshwj xeeb xws li kev sib txuas lus ntawm submarine thiab lub hauv paus. Quantum Kev faib tawm tseem ceeb tuaj yeem tsim cov QEATUM channel ntawm Alice thiab Bob, thiab muab tus yuam sij rau lub sijhawm raws li kev xav tau. Yog tias eavesdropping tshwm sim thaum lub caij xa tuaj tseem ceeb, ob leeg Alice thiab Bob tuaj yeem ntes lawv.

Quantum Kev faib tawm tseem ceeb thiab saib xyuas ib zaug yog cov thev naus laus zis ntawm Quantum kev sib txuas lus nyab xeeb. Nyob rau hauv xyoo tsis ntev los no, cov tsev kawm qib siab tseem ceeb thiab cov kev tshawb fawb tau ua tiav ntau ntawm cov kev sim ntawm cov thev naus laus zis ntawm cov thev naus laus zis.Electro-Optic ModulatorsthiabNqaim kab lis haujlwm lasersTus kheej tsim los ntawm peb lub tuam txhab tau siv dav siv nyob rau hauv Quantum Keyport cov tshuab. Noj cov nce mus txuas ntxiv nce QEEM QUARICAT MINGOTION ua piv txwv, raws li muaj nyob hauv daim duab hauv qab no.

Raws li cov ntsiab cai saum toj no, lub electro-optical modulator (AM, PM) yog ib qho tseem ceeb ntawm cov chaw muag khoom tseem ceeb lossis theem ntawm lub cim hluav taws xob, kom cov lus qhia tawm tuaj yeem kis tau los ntawm lub oxteical quantum. Cov kab ke yuav tsum muaj lub teeb lub teeb sib zog kom muaj qhov siab extinction pultient kom tsim kom tsim lub teeb tsa lub teeb ci ntsa iab.
