I-Quantum Key Distribution (QKD) iyindlela evikelekile yokuxhumana esetshenziselwa umthethosi we-cryptographic obandakanya ama-quantum mechanics.it inika amandla amaqembu amabili ukukhiqiza okubhalwe phansi kwawo kuphela, ongase asetshenziselwe imiyalezo. Kuvame ukubizwa ngokuthi i-Quantum Cryptography, ngoba isibonelo esaziwa kakhulu somsebenzi we-Cryptographic.
Ngenkathi itholakala ngokuthengisa iminyaka eminingi, inqubekela phambili iyaqhubeka nokwenza lezi zinhlelo zihlangene, zishibhile futhi zikwazi ukusebenza amabanga amade. Konke lokhu kubalulekile ekuthakeni kwale technologies ngohulumeni kanye nemboni. Ukuhlanganiswa kwalezi zinhlelo ze-QKD ezingqalasizinda zenethiwekhi ezikhona yinselelo yamanje kanye namaqembu ahlukahlukene wabakhiqizi bemishini yezokuxhumana, abahlinzeki bengqalasizinda ababucayi, ochwepheshe bezokuphepha edijithali, basebenza kulokhu.
I-QKD ihlinzeka ngendlela yokusabalalisa nokwabelana ngezinkinobho eziyimfihlo ezidingekayo ezinkonzweni ze-cryptographic. Ukubaluleka lapha ekuqinisekiseni ukuthi bahlala bangasese, okusho phakathi kwamaqembu okuxhumana. Ukuze wenze lokhu, sincike kulokho okwake kwabonakala njengenkinga yezinhlelo ze-quantum; Uma "ubheka" kubo, noma ubaphazamise nganoma iyiphi indlela, "uphule" izici ze-quantum.
