Kugawa makiyi a Quantum (QKD) ndi njira yolumikizirana yotetezeka yomwe imagwiritsa ntchito njira yolumikizirana ndi ma quantum mechanics. Imathandizira magulu awiri kupanga kiyi yachinsinsi yomwe imadziwika ndi iwo okha, yomwe imatha kugwiritsidwa ntchito kubisa ndi kubisa mauthenga.Nthawi zambiri imatchedwa molakwika quantum cryptography, chifukwa ndi chitsanzo chodziwika bwino cha quantum cryptographic task.
Ngakhale kuti malonda akupezeka kwa zaka zambiri, kupita patsogolo kukupitilira kupanga makinawa kukhala ophatikizika, otsika mtengo, komanso otha kugwira ntchito mtunda wautali.Izi zonse ndizofunikira kwambiri pakutengera matekinoloje awa ndi maboma ndi mafakitale.Kuphatikizika kwa machitidwe a QKDwa muzinthu zomwe zilipo kale ndizovuta zomwe zilipo komanso magulu osiyanasiyana opanga zida zoyankhulirana, opereka chithandizo chofunikira kwambiri, ogwira ntchito pa intaneti, opereka zida za QKD, akatswiri a chitetezo cha digito ndi asayansi, akugwira ntchito pa izi.
QKD imapereka njira yogawa ndikugawana makiyi achinsinsi omwe ali ofunikira pama protocol achinsinsi.Chofunika apa ndikuwonetsetsa kuti zikukhala zachinsinsi, mwachitsanzo, pakati pa magulu olankhulana.Kuti tichite izi, timadalira zomwe poyamba zinkawoneka ngati vuto la machitidwe a quantum;ngati "muwayang'ana" kapena kuwasokoneza mwanjira iliyonse, "mumaswa" makhalidwe a quantum.
