Kugawa makiyi a Quantum (QKD) ndi njira yolumikizirana yotetezeka yomwe imagwiritsa ntchito njira yolumikizirana ya cryptographic yokhudza zigawo za quantum mechanics. Imathandiza magulu awiri kupanga kiyi yachinsinsi yogawana yomwe imadziwika ndi iwo okha, yomwe ingagwiritsidwe ntchito kubisa ndi kuchotsa mauthenga. Nthawi zambiri imatchedwa molakwika quantum cryptography, chifukwa ndi chitsanzo chodziwika bwino cha ntchito ya quantum cryptographic.
Ngakhale kuti zakhala zikupezeka m'masitolo kwa zaka zambiri, kupita patsogolo kukupitilirabe pakupangitsa makinawa kukhala ang'onoang'ono, otsika mtengo, komanso okhoza kugwira ntchito mtunda wautali. Zonsezi ndizofunikira kwambiri kuti maboma ndi mafakitale agwiritse ntchito ukadaulo uwu. Kuphatikiza makinawa a QKD mu zomangamanga za netiweki zomwe zilipo ndi vuto lomwe likukumana nalo pano ndipo magulu osiyanasiyana opanga zida zolumikizirana, opereka chithandizo chofunikira kwambiri, ogwira ntchito pa netiweki, opereka zida za QKD, akatswiri achitetezo cha digito ndi asayansi, akugwira ntchito pa izi.
QKD imapereka njira yogawira ndikugawana makiyi achinsinsi omwe ndi ofunikira pa ma protocol a cryptographic. Kufunika apa ndikuwonetsetsa kuti akukhalabe achinsinsi, mwachitsanzo pakati pa magulu olankhulana. Kuti tichite izi, timadalira zomwe zinkaonedwa ngati vuto la machitidwe a quantum; ngati "muwayang'ana", kapena kuwasokoneza mwanjira iliyonse, "mumaswa" makhalidwe a quantum.
