ʻO ka Quantum key distribution (QKD) kahi ʻano kamaʻilio palekana e hoʻokō ana i kahi protocol cryptographic e pili ana i nā ʻāpana o ka mechanics quantum. Hiki iā ia ke ʻae i nā ʻaoʻao ʻelua e hana i kahi kī huna i kaʻana like ʻia i ʻike ʻia e lākou wale nō, a laila hiki ke hoʻohana ʻia e hoʻopāʻālua a wehe i nā leka. Ua kapa hewa ʻia ʻo ia he quantum cryptography, ʻoiai ʻo ia ka laʻana kaulana loa o kahi hana cryptographic quantum.
ʻOiai ua loaʻa i ke kālepa no nā makahiki he nui, ke hoʻomau nei ka holomua i ka hana ʻana i kēia mau ʻōnaehana i ʻoi aku ka liʻiliʻi, ke kumu kūʻai haʻahaʻa, a hiki ke hana ma nā wahi lōʻihi. He mea koʻikoʻi kēia mau mea a pau no ka hoʻohana ʻana i kēia mau ʻenehana e nā aupuni a me nā ʻoihana. ʻO ka hoʻohui ʻana o kēia mau ʻōnaehana QKD i loko o ke kahua pūnaewele e kū nei ka pilikia o kēia manawa a ʻo nā hui multidisciplinary o nā mea hana lako kelepona, nā mea hoʻolako kahua koʻikoʻi, nā mea lawelawe pūnaewele, nā mea hoʻolako lako QKD, nā loea palekana kikohoʻe a me nā ʻepekema, e hana nei ma kēia.
Hāʻawi ʻo QKD i kahi ala e hāʻawi a kaʻana like ai i nā kī huna e pono ai no nā protocol cryptographic. ʻO ke koʻikoʻi ma ʻaneʻi ka hōʻoia ʻana e noho pilikino lākou, ʻo ia hoʻi ma waena o nā ʻaoʻao e kamaʻilio ana. No ka hana ʻana i kēia, hilinaʻi mākou i ka mea i ʻike mua ʻia he pilikia o nā ʻōnaehana quantum; inā ʻoe e "nānā" iā lākou, a hoʻopilikia paha iā lākou ma kekahi ʻano, "uhaki" ʻoe i nā ʻano quantum.
