Ukusabalalisa ukhiye we-Quantum (i-QKD) kuyindlela yokuxhumana evikelekile esebenzisa iphrothokholi eyimfihlo ehlanganisa izingxenye ze-quantum mechanics.Ivumela amaqembu amabili ukuthi akhiqize ukhiye oyimfihlo owabiwe ongahleliwe owaziwa yiwo kuphela, ongase usetshenziselwe ukubethela nokususa ukubethela imilayezo.Ivamise ukubizwa ngokungalungile ngokuthi i-quantum cryptography, njengoba iyisibonelo esaziwa kakhulu somsebenzi we-quantum cryptographic.
Nakuba kutholakala ukuhweba iminyaka eminingi, inqubekelaphambili iyaqhubeka ekwenzeni lezi zinhlelo zihlangane, zishibhile, futhi zikwazi ukusebenza amabanga amade.Konke lokhu kubalulekile ekuthathweni kwalobu buchwepheshe ngohulumeni nezimboni.Ukuhlanganiswa kwalezi zinhlelo ze-QKD kwingqalasizinda yenethiwekhi ekhona manje kuyinselelo yamanje kanye namaqembu ahlukahlukene abakhiqizi bemishini yezokuxhumana, abahlinzeki bengqalasizinda ebalulekile, abaqhubi benethiwekhi, abahlinzeki bemishini ye-QKD, ochwepheshe bezokuphepha bedijithali nososayensi, basebenza kulokhu.
I-QKD ihlinzeka ngendlela yokusabalalisa nokwabelana ngokhiye abayimfihlo abadingekayo kumaphrothokholi e-cryptographic.Okubalulekile lapha kusekuqinisekiseni ukuthi zihlala ziyimfihlo, okungukuthi phakathi kwezinhlangothi ezixhumanayo.Ukwenza lokhu, sithembele kulokho okwake kwabonwa njengenkinga yezinhlelo ze-quantum;uma "ubheka" kubo, noma ubaphazamisa nganoma iyiphi indlela, "uphula" izici ze-quantum.
